3.3/macppc won't boot off the CD-ROM on an iBook SE

Hello,

(My apologies if this is already documented somewhere, but I couldn't find anything on it on the OpenBSD site or through search engines.)

Having received my new OpenBSD 3.3 CD-ROM set in the mail yesterday, I tried booting disc 2 for macppc on my iBook SE, only to find that it hangs during the boot process. The 3.1 release (the last one I have) booted without any trouble, so something seems to have changed in the interim.

The machine in question is a 366MHz iBook SE -- I don't know if there are any hardware differences between this machine and other iBooks of comparable vintage other than the processor speed, default RAM size, and hard drive size. (My understanding was that it was otherwise identical to the first iBooks at 300MHz, but perhaps that's not the case? Or perhaps 3.3 won't boot on other iBooks as well?)

I've included the dmesg from my iBook when it boots 3.1 (off the CD-ROM from that release), and an excerpt from the dmesg for 3.3 when it tries to boot (unfortunately I can't capture the dmesg for 3.3, since obviously I have nothing to work with, it never finishes booting).

3.1 dmesg:

[ using 206936 bytes of bsd ELF symbol table ] console out [ATY,RageM_Lp]console in [keyboard] ADB found : memaddr 91000000 size 1000000, : consaddr 91000000, : ioaddr 90020000, size 20000: memtag 8000, iotag 8000: cons_width 800 cons_linebytes 800 cons_height 600

3.3 on the other hand gets as far as the following excerpt and then stops (this segment is identical to 3.1, except the last line is incomplete):

ohci0 at pci1 dev 24 function 0 "Apple USB" rev 0x00: irq 27 OHCI version 1.0
usb0 at ohci0: USB revision 1.0
uhub0 at usb0

3.3 freezes at this point, without noting the irq or OHCI version of ohci1. I tried booting several times, but this is always the result. The machine becomes non-repsonsive here, and I have to reset it.

I would guess from comparing the dmesg of 3.1 and 3.3 that something in the latter release (or maybe 3.2) was changed so that the error noted in 3.1 now causes things to halt (but that's just an "uneducated" guess):

ohci1: unsupported OHCI revision
ohci1: init failed, error=4

I'd really like to use OpenBSD 3.3 on my iBook; if there's anything I can do to help (or more information is required), please let me know. Right now I don't have OpenBSD running on my iBook; I just acquired it, and it's running MacOS 9 (shudder).

Do you need more help?
