PCMCIA-related IDE problems on GA-7ZX motherboard

[Charles Briscoe-Smith <cpbs@debian.org>]

Hi,

[Please CC me on any replies; I'm not subscribed to linux-kernel.]

I'm having problems related to using a pcmcia bridge on a desktop PC.
The machine used to contain a TMC TI5-VG+ motherboard with a 400Mhz K6-II.
With the TMC motherboard, everything worked worked fine.  When I upgraded
the machine to a Gigabyte GA-7ZX with 800Mhz Athlon, the CD-writer and
LS-120 floppy on the secondary IDE channel stopped working.  By fiddling
around with the kernel configuration, I've finally narrowed it down to
the PC card drivers; the machine contains a Chase-AT "Duo" ISA-to-PCMCIA
bridge.

What appears to happen is this.  I boot the system:

root@munkustrap:~# cat /proc/cmdline 
BOOT_IMAGE=test ro root=301 BOOT_FILE=/vmlinuz.test hdc=ide-scsi single
root@munkustrap:~# cat /proc/version 
Linux version 2.4.0 (root@munkustrap) (gcc version 2.95.2 20000313 (Debian GNU/Linux)) #1 Tue Jan 16 20:11:06 GMT 2001

I've tried several other kernel versions; some 2.2 series, some 2.4.0-test
series, and also 2.4.1.  They all give the same result.  Logging in in
single-user mode, I can access the CD-ROM drive okay:

root@munkustrap:~# cdir
sr0: CDROM not ready.  Make sure there is a disc in the drive.
nodisc

Then I load the core module:

root@munkustrap:~# insmod /lib/modules/2.4.0/kernel/drivers/pcmcia/pcmcia_core.o
Linux PCMCIA Card Services 3.1.22
  options:  [pci] [cardbus] [pm]
root@munkustrap:~# cdir
sr0: CDROM not ready.  Make sure there is a disc in the drive.
nodisc

At this stage, the CD still works fine.  Then I insert the i82365 module:

root@munkustrap:~# insmod /lib/modules/2.4.0/kernel/drivers/pcmcia/i82365.o poll_interval=100 irq_list=5
Intel PCIC probe: 
  Cirrus PD672x ISA-to-PCMCIA at port 0x3e0 ofs 0x00, 2 sockets
    host opts [0]: [ring] [65/6/0] [1/15/0]
    host opts [1]: [ring] [65/6/0] [1/15/0]
    ISA irqs (default) = 5 polling interval = 1000 ms
charles@munkustrap:~$ cdir
scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 
hdc: lost interrupt
scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 0, lun 0 Request Sense 00 00 00 40 00 
SCSI host 0 abort (pid 0) timed out - resetting
SCSI bus is being reset for host 0 channel 0.
hdc: lost interrupt
(and lots more of the same...)

I've tried with and without poll_interval, and with various irq_lists
("12,13", "10", "5").  All give the same result.  The same happens with
the floppy, /dev/hdd.  /dev/hda is fine, though.

So, it seems that inserting the i82365 module interferes with the
interrupt being used for the secondary IDE channel on the GA-7ZX board,
but doesn't interfere with the secondary IDE channel on the TI5-VG+.

Does anyone know what's going on here?  Can anyone suggest a fix or
a workaround?  (Unloading the pcmcia modules does NOT cause hdc and hdd
to start working, unfortunately.  I have to reboot to get them working
again.)  Failing that, can anyone suggest how I might try to develop a
fix or a workaround?

Some more system details, in case they're of use:

root@munkustrap:~# cat /proc/interrupts

NMI:          0 
ERR:          0

(Also, I know that irqs 3 and 4 are in use by the serial ports.  I think
the rest are free.)
