[1.] One line summary of the problem:
Linux 2.2.10 SMP+2940UW - Kernel panic: VFS: Free block list corrupted
[2.] Full description of the problem/report:
At ramdom intervals the system hangs with kernel panic.
This system was installed on Monday, first hang Friday at 7:00, second one Friday at 17:00.
The system hosts a proxy server that is filling up a partition, perhaps this explains why at first we had no crash (empty disk).
[3.] Keywords (i.e., modules, networking, kernel):
kernel, filesystem, SMP, scsi
[4.] Kernel version (from /proc/version):
Linux version 2.2.10 (root@new) (gcc version 2.7.2.3) #8 SMP Mon Jun 28 21:43:53 MEST 1999
[5.] Output of Oops.. message with symbolic information resolved (see Kernel Mailing List FAQ, Section 1.5):
[6.] A small shell script or example program which triggers the problem (if possible)
not possible! :-)
[7.] Environment
SMP machine with 2 PII 350, 256Mb RAM, adaptec 2940UW, good motherboard (supermicro).
