https://bugzilla.kernel.org/show_bug.cgi?id=31212 Summary: aacraid is generally unstable with newer kernels Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.32, 2.6.37.3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: AACRAID AssignedTo: scsi_drivers-aacraid@xxxxxxxxxxxxxxxxxxxx ReportedBy: nemesis@xxxxxxxxxxxx Regression: No Created an attachment (id=50962) --> (https://bugzilla.kernel.org/attachment.cgi?id=50962) dmesg I have a HP DL380 with an Adaptec 2120S that, many moons ago, never exhibited any problems. Since lenny and squeeze I have had frequent "Host adapter abort request" messages followed by a RAID firmware panic under heavy disk I/O. In 2.6.32 it seemed impossible to recover from these things, it would offline the RAID and disable the system. In 2.6.37.3 it seems better at recovering after a delay, but I am afraid something is wrong at a low level that may corrupt data: [572820.064043] aacraid: Host adapter abort request (2,0,0,0) [572820.149996] aacraid: Host adapter abort request (2,0,0,0) [572820.235786] aacraid: Host adapter abort request (2,0,0,0) [572820.321554] aacraid: Host adapter abort request (2,0,0,0) [572820.407418] aacraid: Host adapter reset request.
