Subject: [2.6.25-rc2-mm1] Oops in __kmalloc

Hi,

while booting up a notebook on 32 bit, this oopses appeared on the console
after ext3 fsck:
http://www.fi.muni.cz/~xslaby/sklad/mem_oops/

It's 2.6.25-rc2-mm1, I can't find similar reports, is this known or hardware
issue (unlikely, 2.6.24.2 seems to be OK)?

I don't recall seeing a similar report and yes, it'll be a kernel bug.

We've fixed a few things and it could be that this will just go away in
next -mm. If it doesn't, a bisection search would be good, thanks.

Well, next -mm is out. Could you test, Jan? [our -mm git is up-to-date]

I don't see your config but if you have CONFIG_SLUB enabled, this is
probably the same problem as:

http://bugzilla.kernel.org/show_bug.cgi?id=10015

which is fixed since 2.6.25-rc2 in mainline.

Sorry for the typo, it's fixed in 2.6.25-rc3.
