Hi
I recently started a thread called "IO APIC IRQ assignment" to find a
way to separate the IRQs assignments for the USB and BT878 chip. In
the meantime, our workaround was to tweak the PCI latency to make the
2 devices work nicely on the same IRQ, but last night, 1 of the 10 PCs
under test crashed.
I apologise in advance for posting the same console stack trace again,
but I figured this problem needed a new topic as it is not related to
IO APIC IRQ Assignment topic. If anyone can guide us to where to look
for the problem, it will be much appreciated. We have 5 x PCs running
2.6.14.2 kernel, and 5 x PCs running 2.6.16.18. This crash happened on
the 2.6.14.2 kernel.
