Strange taskqueue timeouts

[Matthew Dillon]

:Too strange that after a reboot or reset, the disk was completely missing.
:There was no ad4 (or ar0) any more. It appeared again, after powering down
:the box completely.
:
:> Prior to my recent departure from the FreeBSD Project, I documented this
:> common problem.  And no, there is no fix for it; it requires a large
:> amount of time and money (replacing hardware) to troubleshoot.
:
:Thanks! I'll take a close look if this kind of problems appear again.

:Regards,

    Check that all the fans are working and the disk hasn't overheated, too.
    One thing that a big rdist might do is exercise the cpu and disk enough
    to overheat the system if it was not otherwise well fanned.
