Hello,

here comes...

ksymoops 2.4.8 on i686 2.4.22-pre5. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.22-pre5/ (default)
-m /boot/System.map-2.4.22-pre5 (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.

Problem showed up during tar from disk (3ware RAID) to tape (aic-SDLT). Box is completely stable under 2.4.22-pre2, but my long-term bug-report regarding verification errors during tar verify cycle still holds.

Any further information needed? Just tell me...

Stephan
