kernel oops with 2.4.3-xfs

kernel oops with 2.4.3-xfs

[Gerald Weber]

hi,
i use kernel 2.4.3 with xfs (release 1) on a dell poweredge 2450.

it happens about every week that the system completely hangs (network
down,console does not accept
any input,sysreq useless...).
i think this has anything to do with xfs or other fs issues,because kupdated
always uses about 98% of cpu
time.i couldn't report any errors because no oops or something else was
generated until yesterday night:

ksymoops 2.4.0 on i686 2.4.3-XFS.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.3-XFS/ (default)
     -m /boot/System.map-2.4.3-XFS (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

2 warnings issued.  Results may not be reliable.


i'm using a suse7.1 system,the kernel was compiled with gcc-2.95.3.

i'm not sure if this oops has anything to do with xfs or fs in general,but this
is the first oops i ever found
in the logfiles.

if anyone needs more information,please let me know.
the system is a production system and i need to get this thing stable.

please cc me because i'm not subscribed to the list.

regards,

Re: kernel oops with 2.4.3-xfs

[Steve Lord]

Hmm, we 'released' version 1 of XFS against a 2.4.2 base - and packaged
it into a RedHat 7.1 Kernel RPM, we also have a development CVS tree
currently running at 2.4.4. If you are running a production server
with what you describe below, you might want to switch to one of the
other two kernels I mentioned. The development tree just got a fix
which does make xfs much more responsive to cache pruning, and has
numerous other xfs fixes so you might want to use this.
