I'm in the process up converting from RHEL 2.1 to RHEL 4, and have
encountered an issue with the aic7xxx_old driver (5.2.6, as provided
with the RH 2.4.9-34 kernel, and with 2.6.15.5 kernel).
The SCSI card is an Adaptec 2940U card.
Namely, an old SCSI device isn't being seen very often. Maybe 1 in
10 times loading the module. Under the 2.4.18 kernel, it was always
seen using this driver except in the case of hardware/cabling issues.
With the same hardware and OS, but using the new driver (aic7xxx),
the hardware is consistently seen.
I've recompiled the module to enable VERBOSE debugging, and tried
all 4 different seltime values, and it doesn't seem to matter what
the seltime values are. I still get selection timeouts.
Any ideas? I can provide debug logs from /var/log/messages.
If there is a better place to ask, let me know.
I didn't post this with Red Hat since it happens with a vanilla
kernel too.
