The messages above are similar to a > SCSI "busy" status... that's normal. i can confirm that there seems to be a problem with 3ware controllers on 6-STABLE, including a recent one (january 12th). i started getting lockups on a server that was running smoothly on 4-STABLE, but now it locks up regularly, about once a day. the array is not rebuilding, and i don't get any messages in the logs. my controller is also a different model, namely 8506 (twe driver). so far i don't see any correlation with controller activity. i had lockups on a fairly loaded (~50% disk load) controller, and on almost idle (1-5%). nothing is printed to the console and system is unresponsive, except for pings. strange thing is, usually when there is a disk problem, some activity is still possible - e.g., if you have a running shell, you can still at least type or even use commands/work with files in cache. not in this situation, though. i will try to investigate further, maybe try downgrading to 5.x dmesg output: http://pastebin.com/504721 -- Deomid Ryabkov aka Rojer myself@rojer.pp.ru rojer@sysadmins.ru ICQ: 8025844
