Hi all,
I've just got a Gericom laptop (Gericom 1st Supersonic M6T 1200,
also known as Gericom A380) and I'm having alot of trouble getting
the internal peripherals working (all of them are supported using
kernel-included drivers, except the Lucent WinModem, which is
supported using a separate module).
The basic problem is that I've been able to get interrupts assigned to the
peripherals _only_ booting into Windows 2000 (other Windows versions won't
do the trick) _from poweroff_ and then booting into Linux (I think that in
fact it's a broken BIOS problem, but there are no upgrades available yet).
Even then, the soundcard didn't work correctly (I think because of another
IRQ routing problem).
I've tested kernels from RH 7.2 (2.4.7 + RH patches), from Mandrake 8.1
(2.4.8 + MDK patches), clean 2.4.17 and 2.4.18pre1.
The laptop HW configuration is the following:
- Chipset VIA vt82c686b (rev 40) with PIII 1200 stepping 01, 384 MB RAM
- Radeon Mobility
- Accton EN2242 Series MiniPCI Fast Ethernet AAdapter (using tulip driver)
- Lucent Technologies LT Win Modem (using linmodem external module)
- Lucent Technologies IEEE 1394 firewire controller (OHCI compatible, using
OHCI driver)
- VIA 686a AC97 audio (using via82cxxx driver)
- Serial port, IRDA port, parallel port
- 1 atapi HD (/dev/hda)
- 1 atapi CDRW/DVD (/dev/hdc)
The ethernet card, the modem and the firewire controller
all share IRQ 10 (together with 2 Cardbus bridge) under W2000. The sound
device uses IRQ 5 together with the video card and the USB controller.
Under Linux, the soundcard gets assigned IRQ 4 but it doesn't work correctly
and the ethernet card, the modem and the firewire all get
IRQ 0 (= IRQ not found, right?) when not coming from a previous W2000
boot. The Cardbus devices seem to work correctly (I haven't tested them,
though).
I've tried to figure out what's happening enabling the DEBUG #defs
in "linux/arch/i386/kernel/pci-*", but my knowledge of bios32/PCI/chipset
inner workings are non-existent to say the least :-(
I'm adding as attachment the boot messages of a 2.4.17 kernel (with
PCI debug enabled, APM, no ACPI and relevant drivers compiled in) before and
after booting fresh into W2000, together with the respective output of the
"lspci -vv" command. The command line was:
ro root=/dev/hda5 hdc=ide-scsi
I've tried also the "pci=bios", "pci=nobios", "pci=biosirq" boot options
without success.
Has anyone else alread been experiencing that ?
Is there any fix/workaraound/gross hack ?
Thanks for your time.
Bye

Yes, the BIOS provided $PIR table seems broken.
It would be nice if you could try whether ACPI IRQ routing works for you.
To do so, get the latest ACPI (20011218) source release, from
www.sf.net/projects/acpi and apply it to 2.4.17. Then, apply the appended
patch.
Please add "pci=acpiirq" to your kernel command line and send me your
kernel log after a reboot.
