The fibre channel module is: 06:01.0 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 02) 06:01.1 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 02) # lsmod Module Size Used by ... qla2xxx 143584 1 # l /lib/firmware total 244 lrwxrwxrwx 1 root root 21 2007-05-05 22:02 ql2300_fw.bin -> ql2300_fw.bin.3.03.18 With recent kernels filesystem corruption occurs under high disk I/O. I have just tried 2.6.19 and I got the same, but kernel 2.6.18 and before looks safe. The test I use is the following: I first checkout the kernel's git tree: # git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6.git Then # for i in {100..400}; do; rsync -a linux-2.6.git/ c2_$i& done .... waiting for finish # for i in {100..400}; do; rsync -a linux-2.6.git/ c3_$i& done .... waiting for finish # for i in {100..400}; do; rsync -a linux-2.6.git/ c4_$i& done Some error messages: ReiserFS: warning: is_tree_node: node level 32010 does not match to the expected one 1 ReiserFS: sdb1: warning: vs-5150: search_by_key: invalid format found in block 8093723. Fsck? ReiserFS: sdb1: warning: vs-13070: reiserfs_read_locked_inode: i/o failure occurred trying to find stat data of [961831 1064427 0x0 SD] I am able to reproduce this errors. With other filesystems I get similar errors. I suspect a bug in qla2xxx, but I am not sure. Can you help me how to track down this problem? Thanks in advance.
