"scsi0:0:6:0: Attempting to queue an ABORT message" and friends hang

[Jarno Paananen]

Hi,

I've lately come across these messages a bit too many times:

scsi0:0:6:0: Attempting to queue an ABORT message
scsi0:0:6:0: Cmd aborted from QINFIFO
aic7xxx_abort returns 8194
scsi0:0:6:0: Attempting to queue an ABORT message
scsi0:0:6:0: Cmd aborted from QINFIFO
aic7xxx_abort returns 8194

[repeat ad infinitum]

and then all disk activity hangs. Is this a bug in the driver or a
symptom from failing disks/cable or something? It happens on both
my disks (sometimes the 0:6:0 is 0:5:0) so I hope it isn't the
disks. I'm running 2.4.8-ac1 now, but it has come up every now and
then since 2.4.6 kernels at least.
