Hi.
On my machine the ahc (aic) driver times out while probing for devices
on SMP, while it is working on UP.
dmesg says
ahc0: <Adaptec aic7890/91 Ultra2 SCSI adapter> port 0xd000-0xd0ff mem 0xe1000000
-0xe1000fff irq 15 at device 6.0 on pci0
aic7890/91: Wide Channel A, SCSI Id=7, 32/255 SCBs
while booting the SMP kernel it says
(probe0:ahc0:0:0:0) Timedout SCB 9 handled by another timeout
(probe1:ahc0:0:1:0) SCB 0x8 - timed out while idle, SEQADDR == 0x167
sg[0] - Addr 0x7f2f684 : Length -2147483612
(probe1:ahc0:0:1:0) Queuing a BDR SCB
(probe1:ahc0:0:1:0) no longer in timeout, status = 34a
and after some more time will print more timeout messages and will not (at
least not for a few minutes) finish probing or announce any SCSI devices.
devices connected are
da0 at ahc0 bus 0 target 2 lun 0
da0: <IBM DORS-32160 S82C> Fixed Direct Access SCSI-2 device
da0: 10.000MB/s transfers (10.000MHz, offset 15)

da2: 40.000MB/s transfers (20.000MHz, offset 63, 16bit)
da2: 17501MB (35843670 512 byte sectors: 255H 63S/T 2231C)
Is anyone else seeing this ?
Another strange thing is that cdrecord -scanbus tells me

While camcontrol devlist says
<IBM DORS-32160 S82C> at scbus0 target 2 lun 0 (pass0,da0)
<IBM DCAS-34330 S65A> at scbus0 target 3 lun 0 (pass1,da1)
<IBM DDYS-T18350N S80D> at scbus0 target 8 lun 0 (pass2,da2)
<YAMAHA CRW4260 1.0h> at scbus1 target 0 lun 0 (pass3,cd0)
<NEC CD-ROM DRIVE:465 1.03> at scbus1 target 1 lun 0 (pass4,cd1)
Maybe just a bug in cdrecord.
