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:
