reiserfs b0rken on 2.4.22-pre4-ben0 on powerpc ?

[Soeren Sonnenburg]

Hi.

I tried to mount a reiserfs partition (which is connected via firewire
or usb mass storage) and while it mounts ok with 2.4.21-ben2 it hangs
while mounting on 2.4.22-pre4-ben0.

I guess something is broken there... I can get into the kernel debugger
xmon and supply you with a backtrace shot taken with some digital
camera... if that helps.

If it is a known issue what is the solution ?

Thanks,
Soeren.

Sorry, but what is -benX kernel version?

The powermac tree from Benjamin Herrenschmidt, see penguinppc.org or
ftp.kernel.org:/pub/linux/kernel/people/ben for his rsync tree or
patches to the vanilla kernel.

Best,
Soeren.

Please try this (which is in -pre5 and not related to reiserfs)

You are right that patch fixes it.

Pretty strange that it worked on some ext3 partition ... hmmhh.

Thanks a lot,
Soeren.
