Hi,
after finally upgrading our systems from Kernel 2.4 to 2.6 we experienced
problems with the ISDN cards, a hisax driven Sedlbauer Speed Fax+.
A "modprobe hisax type=28 protocol=2" ends in this mess:

==========================================================================
While the output seems to suggest a hardware problem, the same system
loads the hisax driver perfectly on recent 2.4 kernels.
We tried several kernel versions, up to 2.6.21.3
Any hints are appreciated :)
Best,
Thomas

As described, the interrupt handler is registered too late, so early
incoming interrupts lead to the original problem. The patch first disables
the interrupts (byteout(..., 0)), then registers the irq, and finally
enables the irqs again (byteout(..., 2) as was done at the first point
before).
Please note that the patch was developed without access to technical
specifications; the /exact/ meaning of the constants being written to the
registers are unknown.
Patch applies to 2.6.22-rc4.

Presumably whatever writes the driver is doing there are enabling the
card to generate interrupts - in this case the IRQ handler needs to be
registered before this point, and not after..

Thx for your answer. Unfortunately, it didn't help us yet in finding a fix
for the problem.
The first IRQs are received after the call to pci_enable_device, but
before the IRQ handler itself is registered (register_irq). The IRQs seem
to be triggered by the write operations to the card registers
(byteout()/outb() calls around lines 676ff in sedlbauer.c); the IRQ
handler is registered much later, though. The dump above suggests that the
kernel relays the interrupts to the USB handler (on the same IRQ) instead
- which obviously is wrong.
In short:
* pci_enable_device
* writing to card registers -> triggering interrupts
(handler not yet installed -> error)
* register interrupt -> fails, as it already was disabled due to the
errors
Again: thx for your comments. Do you have any further ideas/advice on how
to get the driver running?

Likely a driver problem - the device is using IRQ 11, but the driver
never actually registered a handler for that interrupt (it's not in the
list of handlers, only USB is). Maybe retrieving the interrupt before
pci_enable_device? (I haven't looked at the code in question.)
