Subject: Wrong SCSI bus scanning
Date: Tue, 25 Sep 2001 02:32:41 +0200 [thread overview]
Message-ID: <20010925023241.F14771@lug-owl.de> (raw)
Hi!
For me, SCSI bus # 2 gets double-assigned. Physical layout
is currently:
Bus 0: AIC7xxx (U160 onboard)
- ID0: IBM DDYS-T18350N
Bus 1: AIC7xxx (2nd U160 onboard bus)
- unused
Bus 2: sym53c8xx ('875)
- ID1: PLEXTOR CD-R PX-W1210S
- ID2: PLEXTOR CD-ROM PX-40TS
- ID3: PIONEER DVD-ROM DVD-305
Bus 3: ncr53c8xx ('810)
- ID0: HP CD-Writer 6020
- ID1: PLASMON CDR4220
The U160 controller attaches to my boot disk, so it is compiled-in.
Both other drivers are modules.
When I insert modules for busses #2 and #3, *both* of them get
bus #2 assigned:

...which is obviously wrong. Any suggestion on where to start
to search the bug?
