Hi everyone:

I use AHA2940UW width a HD Seagate ST-36530W (6.5GB)conected at 68 pins, and
one Fujitsu MO 640 MB conected at 50 pins. Both ok instaled and its run ok
under NT 4.0 WS.

But when i tried to use a Linux Red-Hat 5.2 kernel 2.0.36 at boot
time -every time at diferent phase of boot process after SCSI recognition
device- appears this message:

scsi: aborting command due to timeout (pid X) : pid 0, scsi0, channel 0,
id2, lun0
host 0 abort (pid X) time out-reselling bus is being reset

after 3 o 4 times of the reset loop run ok since the next reset loop.

transfer rate of MO is syn negotiate at 5 mbps ond offset at 8.
transfer rate of HD is syn negotiate at 10 mbps ond offset at 8.

The maximum rate of HD is limited by BIOS setup (as recomended by SuSE in
FAQ web Pages)

But don't work on Red Hat. Prehaps because bios can't fix value below 10
mbps.

Can someone help me?
