I've just installed 2.1.0-950726-SNAP, and I'm still having major grief
with the AHA-2940. Basically the system locks up with the SCSI drive
light on; Alt-Fn does nothing. There are no panic messages.
The system:
Gateway 2000 4DX2-66P
PhoenixBIOS v4.03 GPCI 4.03.09
Motherboard: Anigma (?), Saturn Rev 3 chipset I believe
Adaptec AHA-2940
Seagate Barracuda ST31250
Diamond Stealth 64 VRAM PCI
DTC PCI IDE Controller
WD Caviare 540MB IDE
IDE CDROM
SMC Elite Ultra
SoundBlaster 16
(dmesg output is appended below)
I install FreeBSD on the SCSI disk, which has no DOS partition. None
of the IDE stuff is used, although the controller and disk are probed.
The problem first occurred during installation (via NFS) while bin was
being extracted.
I turned the external cache off, and was able to install successfully.
I built a custom kernel, booted it and tried to break it. It wasn't
hard :-( The following:
cd /
tar -cf - usr | (cd /usr/local; tar -xvf -)
caused a lock-up after about 5MB had been copied. /usr and /usr/local
are both in their own partitions.
I reduced the SCSI transfer rate to 5MHz, still with cache disabled,
rebooted and tried again. It got a bit further - about 8MB copied. Again
the system locked up, but this time the BIOS was hosed - I got "CMOS
checksum bad" when I tried to reboot. Joy!
I know that elsewhere the 2940 works well (ftp.cdrom.com). Has anyone
any idea why it should bite me? Motherboard? If so, I'll change it.
Timing problem due to fast disk? (7200rpm, 8ms - but I can't be the only
person using one). BIOS?
I'll be happy to try to obtain some diagnostics on this if someone can
tell me how to go about it.
