Hi, linux-kernel!
I fulfiled the form in the end of the mail, but first I want to describe
it all in other words.
Please, answer to my address too (not only to the list) as long as I'm
not subscribed to it.
Maybe this problem is in hardware -- I don't know...
I have linux-2.4.17. Gzipped .config file is attached.
My computer is AMD K6-200 running as AMD K6-210 :)
I have 64Mb of SGI's SIMM. Motherboard is Acorp with 430tx chipset.
HDD is Seagate 8.4Gb ST38421A.
I use XFree86 v4.0.3, icewm (as a window manager), gkrellm (X' system
monitor), etc
Sometimes when I work kernel panic apears. It usually happens after I
have worked for some time. After that some processes can run, other's
cannot. Sometimes kernel panic calms down after a while and I can work
again as I did before.
I setuped syslogd to dump errors to /dev/tty8. All the times I
remember off Kernel reported Oops there and it had
Call Trace: [cached_lookup+14/80] [link_path_walk+1167/1736]
[getname+94/156] [path_walk+26/28] [__user_walk+53/80]
[sys_lstat64+25/112] [system_call+51/64]
in it.
This time
a) gkrellm disappeared.
b) I exited X.
c) I started X and it finished shortly after starting icewm.
d) I tracked down the problem to icewm's request to /proc/net/ using
strace.
(!) e) ls /proc/net gives me Oops and Segmentation Fault.
Note:
strace ls /proc/net
works OK and I even know now the contents of that directory :).
I ksymoops-ed this problem and found that the problem is in d_lookup
function (see below). Trying to find where it's sources are I got
another kernel panic :). I did
cd /reiser/linux/fs # path to linux sources.
grep d_lookup * -r # and it gave me Oops and SIGSEGVed grep.
Using strace I tracked this problem down to requesting
open("jffs2/gc.c", O_READONLY|O_LARGEFILE)
Now
ls jffs2
also gives me a kernel panic. It's on reiserfs.
I also found a soft link on ext2 (or 3) partition that has the same
side-effect.
Note: this bug is 'not directly reproduceble' -- as soon as I will
reboot the system (I hope) this bug will be gone until some unknown
moment in the future. But it appeared many times and I believe will
come again not once... Sometimes it comes when daily cron's
'whole disk'-work is being done.
Thanx.
==============T H E F O R M========================================
[1.] One line summary of the problem:
File accessing.
[2.] Full description of the problem/report:
Sometimes I get kernel panic.
After it appeared first time until I reboot I have many Oops.
I tracked down what they belong to -- to accessing the files.
Three cases I found this time are:
ls /proc/net # => Oops
ls /reiser/linux/fs/jffs2 #=> Oops
cat qprogdlg.h # => Oops
I think there are more, but these are significant: first one is on
proc, second on reiserfs, third on ext2(3?).
Function that causes Oops is d_lookup or cached_lookup...
[3.] Keywords:
filesystem, file,
[4.] Kernel version (from /proc/version):
Linux version 2.4.17 (tim@zhuchka) (gcc version 2.95.4 20010604 (Debian prerelease)) #1 Чтв Мар 21 22:46:03 MSK 2002
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
Here are three Ksymoopsed Oops describing the mentioned cases. They
differ but not too much.
