Re: problems with sbp2 and sd_mod (ipod firewire harddisk)

[FonkiE]

hi!

i have an ipod too. yesterday everything worked fine. today i updated
from firmware 1.02 to 1.1. now the system crashed with 'modprobe sbp2'.

i tried it with 2.4.17 and 2.4.19-pre1.

what i know is that the mac-partition-map changed. so it may as well be
the the code that handles that which is the problem...

the most info i can get out of logfiles:

then CRASH...

what ipod version do others have? similar problems? how to track it down?

a working version of the logs: (firmware 1.02 if ipod, kernel 2.4.17)
