Subject: page_alloc bug
Date: Fri, 23 Aug 2002 09:05:27 +0200 [thread overview]
Message-ID: <20020823090527.A7715@lemuria.org> (raw)
first time reporting a kernel bug, so please tell me if you need any
other details. I'm following the instructions on kernel.org as closely
as I can.
(1) Problem Summary:
console display of "kernel BUG".
(2) Problem:
For about a week now, the machine displays the bug below in the
morning. The machine runs 24/7, and this bug appears to be happening in
the nighttime. Not every day, not reliably, but occasionally.
I have not yet spotted any ill effects, except that I do not know
whether or not this is caused by this bug, the source of it, or
unrelated. Since the bug is in page_alloc, it may be related:
4 ? Z 0:12 [kswapd <defunct>]
Note that all the information below (/proc/...) may be from well past
the time of the bug. There is no timestamp or other indication as to
when exactly the bug occured, and the machine kept on running.
(3) Keywords:
page_alloc ?
(4) Kernel version:
Linux version 2.4.19 (root@nox.lemuria.org) (gcc version 2.95.4 20011002 (Debian prerelease)) #2 Thu Aug 8 12:05:11 CEST 2002
(5) Output of oops:
not sure if this is it, but here is what is displayed on the console:
kernel BUG at page_alloc.c:91!
invalid operand: 0000
CPU: 0
EIP: 0010:[<c012b96d>] Tainted: P
EFLAGS: 00010282
eax: c1009a38 ebx: c103f20c ecx: c103f20c edx: c020657c
esi: 00000000 edi: 00000004 ebp: 00000175 esp: cfaf9da8
ds: 0018 es: 0018 ss: 0018
Code: 0f 0b 5b 00 53 eb 1d c0 89 d8 2b 05 10 26 26 c0 69 c0 a3 8b
I left out the stack trace. I'm not sure if it is important and there's
no way to cut/paste it. if it's important, I will write it down.
(6) not possible
