Re: 2.6.7-rc1 breaks forcedeth
From: Vincent van de Camp
Date: Sun Jun 06 2004 - 07:56:47 EST
I do not use the forcedeth driver, but I do have IRQ 11 problems with an
nforce2 motherboard. I'm not entirely sure if this is the same problem,
but loading the ehci module (managed by hotplug) triggers the kernel to
disable IRQ 11. Dmesg with some stack traces:

I suspect that the driver should at the very least make sure to

function. I have no
idea how to do that, but it looks like something like
writel(0, base + NvRegIrqMask);
writel(NVREG_IRQSTAT_MASK, base + NvRegIrqStatus);
should probably do it. It would be better to reset the thing
completely,
methinks, but whatever.
I'll add that, but it's only a partial fix: what if ehci_hcd is
loaded
before the forcedeth driver?
Luis, could you apply the patch and boot with it? It should print
something like
forcedeth: irq line 11, Status 0x00000020, Mask 0x00000020
If mask and status are really not zero, then it explains your
problems.
Additionally I try to reset the nic in nv_probe - there were a few
reports seemed to indicate that the nic generates timer interrupts
even
if the mask is zero.
