Hi, I have an Adaptec 71605H HBA that's randomly failing to detect any drives at boot. I have two systems with this HBA, and both are showing the exact same behavior. I can reproduce this randomly about 3 out of 4 times, where most of the time it comes up where "lsscsi" shows no drives attached (other than my boot disk, not attached to this HBA) - but then occasionally it works fine (~1 out of 4 reboots) and detects the drives. On a "good" boot, the kernel messages include: [ 27.575091] pm80xx pm8001_exec_internal_task_abort 834:TMF task timeout. [ 27.754640] sas: --- Exit sas_scsi_recover_host: busy: 0 failed: 0 tries: 1 On a "bad" boot, it doesn't include these messages; instead it hangs for ~60 seconds after "Enter sas_scsi_recover_host busy" and then just continues to boot (and that seems to never recover). It also never cleanly shuts down in this state (it hangs forever on "modprobe -q -r ipmi_devintf" and I have to power-cycle the machine -- I suspect this is more of a symptom that the kernel is busy doing other things - possibly still trying to init scsi - isntead an ipmi-specific issue). I'm happy to test patches/etc on this system if necessary -- and/or if someone can help point me in the right direction, I'd appreciate it.
