Subject: [OOPS] Linux-2.4.20-pre4 with reiserfs
Date: Tue, 11 Mar 2003 22:16:12 +0000 [thread overview]
Message-ID: <200303112216.12359.l.allegrucci@tiscali.it> (raw)
I got this oops running the following:
mkreiserfs /dev/hdb3
mount /dev/hdb3 /test
mkdir /test/d
cd /test
`fsx-linux -c 2 linux-2.4.20.tar.bz2' on a console and
`fsstress -d -d -n 10000 -p 10' on a second console.
The oops happened just few seconds after I run `vmstat 1'
on third console. Reproducible.
ksymoops 2.4.8 on i686 2.4.21-pre4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre4/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
