problems with sbp2 and sd_mod (ipod firewire harddisk)

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)

when is this scheduled for the main kernel? is it already in a pre-patch?

I will be sending the latest source to Linux and Marcello within a day or two.

I see that iPod is seen as a mac disk (partition map).
Is it mounted as an hfs filesystem ? Are you aware of any hfs recent development/bugfix ?

TIA
