Hi everyone,

This is my first time posting to the list, so please forgive any 
mistakes I might make.

I'm currently running 4.9-STABLE without issue on a Dell Precision 420 
Workstation.
The system is dual processor (P3-733) and has an Adaptec SCSI controller 
onboard (aic7899), and 512MB of RDRAM.

I was curious to take a look at the 5-series, so I threw in an older 9GB 
SCSI drive and tried to install 5.2-RELEASE.

Upon inserting the CD, the system starts to come up, but crashes when 
trying to initialize the SCSI drives. I can say that this happens in 
5.1-RELEASE, 5.2-RELEASE, and 5.2.1-RC. If I try to boot in safe mode 
(or if I disable the SCSI controller in the BIOS), the system will come-up.

I have brought-up my 4.9 installation, and it recognizes the drive 
without any problems.

dmesg excerpt follows:
...
Waiting 15 seconds for SCSI devices to settle
ahc1: Timedout SCB already complete, Interrupts may not be functioning.
Infinite interrupt loop, INSTAT = 0(probe16:ahc1:0:1:0): SCB 0x8 - timed out
...
[a dump of the card state has been omitted, but can be provided]

Is this a known issue?
Should I provide more information?
Should I file this as a problem?
Any suggestions?

Thanks so much! I look forward to your suggestions!
