PCI Interrupts not delivered, SiS-964 and SiS-661CX chip set
Last modified: 2008-02-07 23:28:36 EST
Description of problem:
PCI Interrupts are not delivered from Chip set SiS 964 and SiS 661.
cat /proc/interrupts shows the device driver and a count of 1. With debugging
enabled in the driver, dmesg shows the device driver loaded and enabled, and
that the interrupt handler has not been invoked even one time.
Version-Release number of selected component (if applicable):
Fedora Core 6, kernel.i585 (2.6.18)
A pci device that generates interrupts is installed in a computer that has a
SiS 964 and SiS 661CX chip set.
A clean install of Fedora Core 6 is performed.
The interrupt driven device driver, with debugging messages enabled, is loaded
The pci device is activated and generates interrupts.
cat /proc/interrupts shows one interrupt from the pci device.
dmesg shows that the driver has not received any interrupts.
cat /proc/interrupts normally shows thousands of interrupts in a short time.
dmesg shows messages from the driver's interrupt handler.
The distribution, device driver, and pci device, are installed on a different,
older, computer. On that older hardware, cat /proc/interrupts shows thousands
of interrupts and dmesg shows similarly many messages from the driver's

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug, however this version of Fedora is no longer
Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.
Thanks for using Fedora!
