>Environment:
(cannot be obtained) Cyrix 5x86/100 with UMC8881/8886 PCI chip set. 24 MB RAM.
>Description:
At Kernel boot time, the sym driver hangs the kernel when probing devices. The last lines I see are (not verbatim):
1. sending SCSI reset
2. waiting 15 seconds for SCSI devices to settle
3. sym0:0 ERROR (81:0) (8-0-0) (0/5) @ (mem 8:f000f7c8)
4. register dump (not copied here)
It's a DC-390U card, which has a Symbios 53C875 manufactured 9752R. The DC-390U has two 50-pin (narrow SCSI) connectors.
The only attached device is a Plextor PX-20 TSi CD-ROM at unit #2 (the adaptor has unit #7). PCI IRQ is unshared. The Plextor is terminated and is detected at boot time or by NetBSD 1.5.
The card is fine with NetBSD 1.5 or Linux 2.2/2.4. The card is also fine in a newer main board (Gigabyte 7ZX-R, with Duron/700 and VIA KT133 chip set).
