After an upgrade from 3.4 to 4.1.1 I started to see hangs with my
Adaptec SCSI pccard. So, I cvsup'ed to 4.2-BETA to see what would
happen. So far, no luck.
Here's what happens. I insert the card (with a Zip drive attached) and
get the kernel messages:
pccard: card inserted, slot 1
aic1: <Adaptec 6260/6360 SCSI controller> at port 0x340-0x35f irq 11 \
slot 1 on pccard1
aic1: aic6360, dma, disconnection, parity check
At this point, nothing happens. The machine looks to be hung, but
apparently it isn't quite yet since it comes to life when I pull the
card out only to say:
(probe6:-1065184176:-1010556672:6:0): ccb 0xc084ec00 - timed \
out, phase 0xff, state 4
and then it promptly drops into the debugger:
Fatal trap 12: page fault while in kernel mode

The pccard relevant dmesg output is:
pcic-pci0: <Cirrus Logic PD6729/6730 PC-Card Controller> port \
0x3e0-0x3e3 at device 4.0 on pci0
...

pcic0: Polling mode
pccard0: <PC Card bus -- kludge version> on pcic0
pccard1: <PC Card bus -- kludge version> on pcic0
The kernel config is:
...
device scbus # SCSI bus (required)
device da # Direct Access (disks)
device cd # CD
device pass # Passthrough device (direct SCSI access)
# CAM options
options SCSI_DELAY=8000 # Be pessimistic about Joe SCSI device
...
device aic0 at isa?
...
device card
device pcic0 at isa? port 0x3e0 iomem 0xd0000 # polling
The pccard.conf only contains an irq line, otherwise it's
/etc/defaults all the way.
