[PATCH] aic94xx: asd_clear_nexus should fail if the cleared task does not complete

2007-05-16 Thread Darrick J. Wong
Every so often, the driver will call asd_clear_nexus to clean out a task. It is supposed to be the case that the CLEAR NEXUS does not go on the done list until after the task itself has been put on the done list, but for some reason this doesn't always happen. Thus, the wait_for_completion_timeout

RE: Dell CERC ATA100/4ch support

2007-05-16 Thread Leigh Blackwell
Hi James, I'm running FW 6.62 and the latest megaraid doesn't detect the controller. The suggestion made on the bug list was to roll back the firmware 6.61 which I am unsure on doing, as Dell are not going to advocate flashing a bios with a firmware not formerly built for that machine (1600SC).
