I am a new user having just installed OpenBSD for the first time. I am
having trouble with my PCMCIA cards. I have 2 cards, both 3COM, and two
PCMCIA slots (TI-PCI1130, see dmesg below).
I am currently having two issues: system hangs in bios after reboot and
kernel panics when pcmcia card is removed.
I am willing to open up 1 or more bug reports if these cannot be easily
resolved, but since my last problem involved using floppyB to boot the
system instead of floppyC, I wanted to make sure this was a real issue
instead of a "new user doesn't know what he is doing issue".
Both problems are easily reproducable, so I can easily gather more
information.
Details:
Issue 1:
My system always boots fine from a powered down state, but hangs in the
bios after a reboot (type reboot at the cmd prompt). The reboot hangs
right after it initalizes the mouse and right before it checks the save to
disk feature. Powering down and back up causes the system to boot
correctly. I know what you are thinking: This is a hardware issue not an
openbsd issue, but hear me out. If I boot the system of a Win95 rescue
disk, the system does not hang. When I had slackware installed on the
system 1 week ago, it did not hang. And here is kicker: it only hangs
when a pcmcia card is in the slot immediately before openbsd syncs disks
to reboot.
Consider the following senerios:
1) Booted to msdos and rebooted: No hang
2) Booted to openbsd and rebooted (card in slot): Hang
3) Booted to openbsd and rebooted (no card in slot): No hang
4) Booted to openbsd and rebooted (no card on boot, inserted after
rc.shutdown is complete, but before kernel syncs disks. Insertion mesg
printed to the screen by the kernel): Hang
5) Booted to openbsd and rebooted (card on boot, removed after rc.shutdown
is complete, but before kernel syncs disks. Detach mesg printed to the
screen by the kernel): No hang
Notice the last two cases prove that it is the state of the card when
openbsd begins the reboot cycle and has nothing to do with the state of
the card during the actual reboot. It seems that openbsd is putting the
hardware into a weird state that prevents the bios from properly booting.
Interrupt related? maybe?
Insert mesg:
ep1 at pcmcia1 function 0 "3Com, 3C574-TX Fast EtherLink PC Card, A" port
0x340/32, irq 5: address 00:10:4b:f4:b5:57
tqphy0 at ep1 phy 0: 78Q2120 10/100 PHY, rev. 10
Detach mesg:

The diff of the dmesg of the system booted with and without card is as
follows (for quick refence, full dmesgs below):

Notice that sometimes irq 5 is used and sometimes irq 9 is used. The
system hands on reboot regardless of which irq openbsd selects.
Issue 2:
The top pcmcia slot does not seem to work with openbsd. The lower slot
works with both of the cards with no issues. If a card is in the top slot
upon boot (or inserted after boot), the kernel is not able to configure
the card and ignores it. When the card is removed a kernel page fault
error is printed to the screen and a dds> prompt is given. This is true
for either card.
This issue is repeatable, the same fault occurs every time, with only
slightly different pointer values in the trace.
Here is the detailed info for the fault
(copied by hand, could contain typos):
Upon insert:
ep1 at pcmcia0 function 0 "3Com, 3C574-TX Fast EtherLink PC Card, A" port
0x340/32, irq 5: address 02:01:02:01:02:01
wrote 7ff to TX_AWAIL_THRESH, read back 4057. Interface disabled
Upon removal of card no detach message is printed, instead:
