2.0.34 + aic7xxx = total failure...

[Vincent Cojot]

Hello Everyone,

	I juste compiled 2.0.34 (with the same configuration I used for
2.0.33) but this is a no go.. Upon bootup, the kernel probes the SCSI
channels and then starts an endless loop of messages like this one:

(SCSI1:-1:-1:-1) Bad scbptr 16 during SELTO
(SCSI1:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
	SCSISEQ = 0x5a SEQADDR = 0x8 SSTAT0 = 0x10 SSTAT1 = 0x8a

It keeps scrolling and once every ten (or so) messages a different message
appears, that includes:

timeout pid27, scsi1, channel0, id 6, lun 0....

I've been using that machine with stable kernels for almost two years with
my 3940 and I have added a 2940UW a year ago, no problems so far until
2.0.34... Any idea what's going on?
