pccard kernel config for OmniBook 500
Najib Ninaba
Is there anybody on the list who has a working pccard configuration for
4.4-STABLE on HP OmniBook 500? I realised that in my kernel config file,
it has (I'm typing from memory here..):
device pcic0 at isa? irq 0 port ... # continues on
What irq should I assign for this particular notebook? And what irqs
should be on /etc/pccard.conf? From dmesg and vmstat -i, seems like the
only available irqs seems to be 9 and 11.
Thanks in advance.
Regards,

I believe the default entry with the following line in /boot/loader.conf
will work:
hw.pcic.init_routing=1
It works for me on -current and the support is pretty near identical at
this point.

I've tried the below-mentioned line without any success. It boots up
normally but still freezes at the point when I plug in my aironet 350
card or ibm modem card. Any other leads?

Try -stable, if you aren't already, otherwise no. If I had acess to
one of these beasts, then maybe I could figure out the problem...

Hmm, odd. It's definatly working here in -current. I was using an
Aironet 340 quite a bit at a confrence last week. Here's what my hint's
file says about the pcic (this translates to the kernel config line
in stable.)
hint.pcic.0.at="isa"
# hint.pcic.0.irq="10" # Default to polling
hint.pcic.0.port="0x3e0"
hint.pcic.0.maddr="0xd0000"

I have access to one now. I have the exact same symptoms with a freshly
installed 4.4-release. It will not even mount a disk when not
using it in polling mode. init_routing=1 also does not seem to make
an effect. The very moment a card is inserted, the machine freezes.
But not solidly! I can go to DDB.
Problem is that I do not have a docking station and thus no serial port
so I cannot use remote gdb on it.
a trace gives that it was in doreti() and eip=0xc029dc70 which is the entry
point of doreti()
What is really funny is that my notebook automatically suspended to disk
(hibernate) during this debugging due to a low battery. When it
came back, the hang was over!?
In fact, after that I could insert other cards as well.
I tried some more and when the system hangs, pressing the suspend
key (either normal suspend or hibernate) does not work anymore.
I also tried rebooting a machine and do a normal suspend after which
I inserted the card. That does not work either.
If the card was already inserted at boot time the system does not
hang, and the card is correctly seen. However, in that case, removal
of the card hangs the machine.
If I hybernate the system and afterwards insert a card it also hangs.
If I could help in anyway debugging this problem I'd surely like to.

a number of times, the system 'unhangs' itsself and card insertion and removal
are working correctly.
Looking at vmstat -i aftrewards, I see a ridiculous amount of interrupts
on irq 10 (assigned to the builtin xl0).
If I set hw.pcic.irq=10 the booting failes with a panic (cant route ISA CSC
interrupt followed by panic: resource_list_release: can't find resource).
I tried again rebooting with hw.pcic.init_routing=1 and hw.pcic.intr_path=2
It hangs as before. The funny thing is the if I go to the debugger,
I see all input I typed. It thus looks like the screen is no longer
updated. Yet that is not the complete story. What I tried next was
to press return to get a single user /bin/sh and type echo ctrl-G.
I got a beep but the beep never stopped. Using ddb again to use the 'n'
trick resulted after a couple of time in a crash of the sh !?

I had an irc session with Warner Losh and a patch has been made to address
the problem. After the patch, you should no longer use hw.pcic.intr_path=1
The patch has just been committed. (you need version 1.1.2.6
of sys/i386/isa/pci_cfgreg.c)

It worked! Thanks, Warner for solving it and Guido for chasing the bug
;) Finally I can use this notebook for some real work. Thanks again, guys.
