Hallo,
I want to report multiple crashes while using last stable kernel, the message
it gives is:
--------------------
Unable to handle kernel paging request at virtual address 45ca6234
printing eip:

--------------------
Then it refuses to do "anything reasonable" (probably forking a new thread),
but ping works and some applications are partially running (e.g. Apache
serves static page, but not CGI). No user can log in.
It prints the message above multiple times, probably at each atempt to do
something. Sometimes (not the first time) it also writes "Bug: ... twice..."
(I don't remember it, sorry, it isn't written in messages).
On the machine are large blocks of shared memory (hundreds of MB, usually
larger than default SHMMAX, which is now set to 256MB), crash happened while
processing large amounts of data (few GB, hundreds of MB RAM used).
Other info: Red Hat Linux 7.3, kernel 2.4.19 from kernel.org, single Athlon
XP, compiled with Athlon processor option and "4GB" memory setting.
If you need more information, feel free to ask me. Do you know what
happened and if it can be fixed?
Thanks,
Michal Illich

both lsmod and ksyms produce no output, I think this is ok in case of lsmod,
because everything is compiled in. I don't know if it is ok with ksyms; if

See REPORTING-BUGS in the kernel source tree, and run the first oops it
logged through the ksymoops tool. That'll make it a lot easier to see
what happened.

Happened again, now with "kernel BUG at buffer.c:510!" message.
Everything same as before, except:
(a) kernel was recompiled without high memory option
(b) machine was running but not responding at all (no ping)
Seems quite serious to me, any ideas?

Looks very much like random memory corruption. Could be many things.
Does the box pass memtest86 ?

It just passed memtest-2.93.1 (I don't have physical access to machine to
run standalone test). BIOS memcheck also runs ok. It usually crashes after
1-5 days, in the meantime all programs run perfectly.
