Hi all! Actually I am facing the same problem as Mario. In my case, it is an Adaptec 5405 Raid Controller running under Debian Lenny and Kernel 2.6.26-13lenny2 with the aacraid module that comes with that kernel. I am using only XFS as a filesystem, some partitions residing on a dm-crypt volume. Under heavy load, I was facing severe problems:

The partition /dev/sda6 is formatted with XFS: xfs_info /dev/sda6 yields: meta-data=/dev/sda6 isize=256 agcount=4, agsize=1221440 blks = sectsz=512 attr=2 data = bsize=4096 blocks=4885760, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 log =internal bsize=4096 blocks=16384, version=2 = sectsz=512 sunit=0 blks, lazy-count=0 realtime =none extsz=4096 blocks=0, rtextents=0 It was mounted as follows: /dev/sda6 on /usr type xfs (rw,noatime,logbsize=256k,logbufs=8) Now, at the time the error occurs, there was nothing special going on in /usr: No copying, nothing except the usual read accesses when starting applications and the Adaptec Storage Manager running (which somehow resides in /usr/StorMan/ and stores some (not very useful) logs there). However, each time the error occurred, I copied a lot of data between two partitions which are located on different logical arrays and on different physical drives than /dev/sda. In my case, the error slowed down the system such that it nearly freezes. It seems that the Raid-Controller (or the driver) where restarted. During this time, I wanted to check what's happening. However, the usual commands were not executed but refused due to lack of memory and later, the binaries where not found any more (which might be due to XFS stopping on /usr). Does anyone else have these problems? I cannot tell when it first occurred, as the hardware is only two weeks old; so I do not have experience with this combination, yet. Could anyone give a hint of how to find out, whether it's a bug related only to aacraid, or to the aacraid/XFS combination?
