In current as of today, /stand/sysinstall generates the following kernel
panic when probing for devices...

--- (typed manually from console) ---

fatal trap 12:  page fault while in kernel mode
fault virtual addres = 0x26c80
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc017309e
stack pointer = 0x10:0xc8782d04
frame pointer = 0x10:0xc8782d04
code segment = base 0x0, limit 0xfffff, type 0x1b
              = DPL 0, pres 1, def32 1, gram 1
processor eflags  = interrupt enabled, resume, IOPL = 0
current process = 163 (sysinstall)
interrupt mask = none
trap number = 12
panic: page fault

scsi part from dmesg:

da0 at ahc0 bus 0 target 10 lun 0
da0: <QUANTUM ATLAS IV 9 WLS 0909> Fixed Direct Access SCSI-3 device 
da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing

WARNING: / was not properly dismounted

cd0: 10.000MB/s transfers (10.000MHz, offset 15)
cd0: Attempt to query device size failed: NOT READY, Medium not present

Notice the cd1: lines, its a CDR (HP 4020i) which is not recognized
because SCSI_DELAY
was too short in kernel config.

When I raise it too 15000 instead of 150 the cd1 is recognized on
And the panic went away, thats not the problem.

My question is:
Is the device entry removed ok from the system like dmesg says,
sysinstall seems
to still find something there when probing, and crashes the system.

The scsi controller is a ahc type (onboard Asus P2B-S).
