Description of problem:
Two SCSI stacks each connected to a AVA2906 (same machine). Boot up detect
correct. When copying large files (>50MB) after 70MB or so is transferred bus
reset request start occuring. Only coarse of action is hard boot (reset button).
If left unattended (2.5+ hours) system locks up hard complaining about an
interrupt. aic7xxx_old produces the same result. After replacement of first
AVA2906 with Tekram 315U no problem copying files on first SCSI stack to other
drives (IDI and SCSI:0) but not SCSI:1 (still AVA2906 controlled.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Initiate (50MB+) cp or mv of a large file on a SCSI drive.
Actual Results: Perpetual reset requests coupled with very slow system response.
Commands especially ls or df, executed in another shell hang for
an extended time before responding.
Expected Results: Copy or move to successfully complete without complaint.

Should I simply upgrade to 7.3 and see if the problem goes away or becomes 64699?
