>Category: kern
>Synopsis: Problem about BT driver for PCI
>Confidential: yes
>Severity: critical
>Priority: high
>Responsible: freebsd-bugs
>State: open
>Class: sw-bug
>Submitter-Id: current-users
>Arrival-Date: Sat Feb 17 22:10:01 PST 1996

>Originator: Kensaku Masuda
>Organization:
Private
>Release: FreeBSD 2.2-960130-SNAP i386
>Environment:
CPU: Pentium-90
MEMORY: 32MB
DISK: 1GB * 2 + 730MB
SCSI CARD: BT-946 & NCR810
>Description:
BT driver can not look up BT-946 PCI card, and driver
don't find old revision BT-946. Ex) PCI product ID 0x0140.
And Mother-board select the shared IRQ, driver will confusing.
bt0 <Buslogic 946 SCSI host adapter> rev 0 int a irq 9 on pci0:17
.
.
ncr0 <ncr 53c810 scsi> rev 2 int a irq 9 on pci 0:18
>How-To-Repeat:
Use all SCSI controller at one time, system will hung up/system down.
>Fix:
I make a patch.
