Hi, I am wondering if any other Buslogic BT-948 users out there are
experiencing this problem.  On a Dual P2 machine running up to 3.0-SNAP i
had my workstations running perfect (Dual pentium at home, same card and 6
gig quantum scsi)  Upon installing 3.0-RELEASE, i started to get scsi
timeouts on both boxes, a la:

Homer.Web-Ex.com kernel log messages:

> bt0: No longer in timeout
> swap_pager: indefinite wait buffer: device: 0x20401, blkno: 432, size:

I initially contacted the developers to report a bug, which they
acknowledged the 'flakiness' of the buslogic driver, and urged me to
upgrade to a post 3.0-RELEASE SNAP, which I did, and kept upgrading to
3.1-RELEASE, with no resolution to the problem.  The timeouts can last up
to 30 seconds, freezing the machines console and Xwindows, but queueing up
all kbd and mouse inputs.  I am wondering since the developers
acknowledged this back in (October?) if anyone has a solution for it.

Thanks.
