Did you all see that the Croc Hunter Simeon Penev wrote:
Matter of approach. I would not disable an IRQ until there had been some number of uncaught interrupts in a row, others feel the number is one. But there really is an interrupt, so it's probably not a "bug" in that sense.Hi Bill, thank you for the fast reply! Bill Davidsen wrote:Although IRQ7 is traditionally LP, it seems to get identified for almost any unexpected interrupt. I knew why once, but I haven't seen this for some time. The real problem is that the kernel disables the IRQ, making the system unusable. You can try any of several things: - try the last 2.6.16 kernel - remove the IRQ disable code, or add a counter. It happens only once on many machines, as something comes ready.I'll try that, but actually i wanted to help fix the problem if it's a bug with the kernel.
Noted, but "just for information" would let you see if the speedstep was the cause, or at least contributed. That would help run it down.- disable any CPU speed stuff you have running (just for information)Yes, i'm using cpufreq, but it's a feature i'm not willing to give away because the laptop is more silent. The fan works less.
I have a machine which does zero or one of these, so I'm familiar with the problem. I am running an older kernel which whines but doesn't disable, and since I don't need IRQ7 I wouldn't be too unhappy if it did disable. But I think there's an underlying hardware issue, or at least hardware to driver mismatch. Since you said irqpoll causes problems there's definitely something not working right.Yes, that's a shotgun approach, I'm still running 126.96.36.1991 on FC4 because later kernels don't init the video or wireless correctly.Thank you once again.
