I don't think that you can keep your 32-bit raid/LVM setup, but I don't
know.  Your safest option is to backup your /home (you do this anyway,
right), and do a clean reinstall.

Yes.  That's what crossover is for.  Purchasing a copy of
crossover will support the development of wine.

Please try to file bug reports at

http://qa.openoffice.org/

with example documents (ideally reduced to simple cases).
You might search for existing bug reports there first to avoid
duplication.

Browsing around to look for potential problems with the VIA chipset driver, I
came upon this:


http://www.tiny.cc/xORCV

(see the last post in the thread)



Apparently, I am not the only one getting this kind of CRC errors on the
primary IDE interface (and I do happen to have this exact motherboard:
ABIT KT7). I will look if there are still some BIOS updates that may change
something.

Take a look at the /etc/udev/rules.d/z25_persistent-net.rules file.

I had a problem with a laptop, because of a lot of testing I was
doing, that thought the ethernet card was eth6.  So ifup eth0 didn't
work but ifup eth6 did.  I repaired that file and now so that eth0 
was the only ethernet interface and all is well.

Subject:  working with two nics (lan and wlan)
Message-ID: <f926le$mjq$1@sea.gmane.org>
Content-Type:  text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding:  7bit

Hello,

I have a headless machine on my home network with a LAN card and a 
wireless card. If my lan cable is connected to its lan card, it gets an 
IP automatically from my firewall machine. But if I activate the 
wireless card, the networking seems to hang or freeze. My lan card is on 
192.168.0.x network and the wireless card is on 192.168.5.x network.

Is there any way I can have both the cards active and networking 
working? Perhaps by specifying somewhere which network has the higher 
priority? This is so because there are many situations where I sometimes 
want both cards up, mainly while trying out various wireless drivers 
with my wireless card. Another situation when I want to transfer huge 
amounts data via the wired network (higher speed) to other machines on 
the local network.

Alternatively, I suppose ifplugd can handle multiple cards at the same 
time. In my situations, can it be configured to use wlan card if it is 
up, else to use the lan card?

Thanks,
->HS

I think you are right. The fan malfunction is probably not the cause,
since it is mounted on north bridge, and IDE controler is in south
bridge, that doesn't need a fan.

So, replace a motherboard.

Yes. Unlike true 64-bit architectures like PowerPC, there is a penalty
for executing 32 bit code on amd64/em64t processors. This is why the
amd64 port of Debian has an all 64-bit user land, whereas other 64-bit
ports of Linux and other operating systems generally have mostly a
32-bit user land and compile only applications that would benefit for
64-bit.

I suspect many of the bad experiences with XFS were using IDE drives on 
32-bit x86 hardware.  XFS was originally developed on RISC hardware, and 
did not fit well with register-starved hardware.  Red Hat in particular 
has worked hard to run with 4k stacks, and XFS users have had to build 
kernels with larger stack size.  The xfsrepair tool needed ample 
resources, so if you had a problem with XFS on a typical system (PIII with 
256M) you had to move the disk to a better box to sort things out.

I use SGI IRIX workstations for remote sensing.  The filesystems are all 
XFS.  Over the years I've had lots of disks fail, and also several SCSI 
controllers.  Often the first sign of hardware problems is errors from 
fsr.  Since the system disks were the oldest, most of the workstations 
have crashed when the the root filesystem went poof, but the other (data) 
filesystems were recovered with minimal problems.

I did have the experience of working on a program only to have big chunks 
of an XFS filesystem on a RAID (5 9G SCSI disks) go poof when the 
controller for the external SCSI failed.  I moved the RAID to another box 
and what was left of the XFS filesystem was fine.

Let us know how you feel once you have experienced a few hardware 
failures.

I also have the ABIT KT7 and it has gone from kernels 2.4.27 ->
2.6.18-4 with no CRC errors showing up at all.  It's only been running
for 5-6 years.  CPU Fan has been changed twice but other then that,
its fine.

Penalty?  Absolutely fscking not!!!!  The A64 processes 32 bit code
at a similar speed to "regular" Athlon CPUs.

Do you have any sources for this? I remember quite distinctly seeing
on a mailing list, I think it was debian-powerpc in fact, that the
only reason that AMD64 operating systems have an all-64-bit user land
is because there is a penalty for executing 32-bit code, one which is
not present on other true 64-bit architectures. 64-bit code /does/ use
more memory, so it is advantageous to have a mixed userland if you can
afford it--e.g. only compiling applications that will benefit from
64-bit into 64-bit executables. This is what the OSes for other 64-bit
architectures do.

Perhaps the penalty is only under a 64-bit kernel...

The rainbow color effect can also be caused by RGB subpixel hinting,
which is an Xft option. Check the output of

xrdb -query | grep Xft

for the Xft.rgba setting. You can change the Xft settings by doing
things like:

echo "Xft.rgba: none" | xrdb -merge

You have to restart the affected application(s) to see the effect of the
changed settings.

Well, wikipedia says ;), the bitwise-inverted umask is bitwise ANDed with the *default "full permission"*, i.e. 666 for files and 777 for dirs. This should mean, 0666 and 0777, if I am understanding it right (see interpretation for missing digits in chmod(1)). Thus:

000 110 110 110 AND
not(000 010 010 010) =
000 110 110 110 AND
111 101 101 101 = 0444

For dirs, the result is 0555.

That's really strange ... but I'm pretty sure that's not debian-specific (as I found this on forums for all kinds of distros).

For newbies however, it might not be that easy to install... you need to make a package for stable yourself. On the other hand, if you'd need it, I can just do an update/recompile here on my system and send the resulting package to you via email.

Yep, that's a good hint: ntfs-3g ver 1.516 (slightly outdated) is available if you add the line:

deb http://www.backports.org/debian etch-backports main contrib non-free

into your /etc/apt/sources.list, do apt-get update, and then install.
