Hi scsi team,

Errors occured on my -current box (from 98.06.16)...

The context: compiling kde with cpp1plus, netscape running, swaping (25%)

I had no seach errors with CAM from 98.04.13. Now the SCSI stack is the
old SCSI2 dated Jun 16 (needed for ppbus and ZIP support).

The SCSI controller is configured "Wide disabled, 10MHz sync for the IBM disk"

The problems seem to appear only under heavy load.

Any test I could do to help?

Thanks in advance.

Here is the config:
