2.4.24 AIC7xxx kernel messages

[Paul Armor]

Hi all,

Please include me in responses, as I'm not currently subscribed.

Googling and searching various archives, I can't find more than passing 
references to my problem, so I'll ask here.  Has anyone else seen anything 
like this, or can anyone offer suggestions as to what may be wrong?  I've 
got an Adaptec 29160, off of which I've got 4 Promise UltraTrak SX8000's, 
across which I'm striping software RAID.  Sometimes, when under heavy 
load, the kernel will log lot's of messages, starting with:

Mar  5 03:47:15 storage2 kernel: scsi0:0:0:0: Attempting to queue an ABORT 
message
Mar  5 03:47:15 storage2 kernel: CDB: 0x28 0x0 0x27 0xaa 0xe5 0x57 0x0 0x0 
0x10 0x0
Mar  5 03:47:15 storage2 kernel: scsi0: At time of recovery, card was not 
paused
Mar  5 03:47:15 storage2 kernel: >>>>>>>>>>>>>>>>>> Dump Card State Begins 
<<<<<<<<<<<<<<<<<
Mar  5 03:47:15 storage2 kernel: scsi0: Dumping Card State in Data-in 
phase, at SEQADDR 0x54
Mar  5 03:47:15 storage2 kernel: Card was paused


...after which it will list SCB stats and info.
	This last occurance started after the machine had been copying 
data from one striped partition to another (it was ~250GB/1.1TB complete), 
and the log messages stopped ~11 minutes later; and the cp has continued.  
It seems as though the card/kernel/external arrays will work well together 
for many hours, get into this state for a few minutes, then work for many 
more hours, etc...  Any comments or suggestions would be GREATLY 
appreciated.

Here is the config:
