It's crashing in module unload, and it appears that the module is
freeing things which were not allocated (or freeing something twice).
It's a module bug --- report it on linux-kernel.  This does not look
like a mm bug.

Cheers,
 Stephen

Hi,

Forwarding to linux-mm since Riel does not read linux-kernel any more...

hi,

I'm running the 2.4.3 kernel and my system always (!) crashes when I try
to generate the "Linux kernel poster" from lgp.linuxcare.com.au. After
working for one hour, the kernel printed this message:

I think there should be more, but it stopped at this point.

Do you need more information about the system?

Thank you, Felix

There are some known bugs in the 2.4 memory management.
Does 2.4.3-ac<latest> fix this ?

(note: 2.4.3-ac<latest> isn't stable/safe either, but
people are working on it and it would be cool to know
if at least this bug has been fixed)

I tried 2.4.4-pre1 and it showed up again (when there was high disk IO):

this was in the syslog:
kernel BUG at page_alloc.c:75!
invalid operand: 0000
CPU:    0
EIP:    0010:[__free_pages_ok+62/784]

ds: 0018   es: 0018   ss: 0018

on the screen there was something like:
panic ... in interrupt handler, not syncing ...

I hope this helps.

Grussle, Felix
