panic: ffs_clusteralloc: map mismatch
Several times, under heavy disk load, my box panicked. I've built finally
debugging kernel on
FreeBSD shuttle.svib.ru 3.0-19990619-STABLE FreeBSD 3.0-19990619-STABLE #0: Thu Jun 24 21:26:37 MSD 1999 root@shuttle.svib.ru:/mnt/usr/src/sys/compile/SHUTTLE i386,
and easily reproduced the crash with two dd's copying data from two CD-ROMs
to one disk.
Here are my dmesg, kernel config and backtrace.
Please help.
Alex.
