FreeBSD tobermory 4.1.1-STABLE FreeBSD 4.1.1-STABLE #0: Fri Oct 20 13:12:24 GMT 2000 root@tobermory:/usr/src/sys/compile/TOBERMORY i386
>Description:
it appears that advansys ultra2 scsi controller (tested with model ASB3940U2W) code is
hardwired to 3 bit SCSI IDs, causing hangup during boot if more than
3 bits worth of drives are present (or, presumably, any drive
with an id higher than 7).
dmesg:
adw0: <AdvanSys 38C0800 Ultra2 SCSI Adapter> port 0xd800-0xd8ff mem 0xff8ffc00-0xff8ffcff irq 9 at device 11.0 on pci1
adw0: SCSI ID 0, High & Low SE Term Enabled, LVD Term Enabled, Queue Depth 253
(yes, I know having it set to SCSI id 0 is weird, but we have to because of
the way the external drive chassis autonumbers).
>How-To-Repeat:
attach more than 7 scsi drives to an advansys controller.
>Fix:
the following patch was our attempt at a quick fix, which didn't work, but
it's a start... :)
