Re: USB related commit leads to hung systems if USB-IRQ=Disabled in BIOS
In my bios I have PnPOS=NO, USB-IRQ=Disabled. The commit below results in a PCI interrupt storm and a terminally wedged system right after interrupts are enabled. This would be a bug in the UHCI or OHCI driver then. You can avoid it by not running the driver.

I should have mentioned; you can probably also avoid it by letting your BIOS give the USB controller an IRQ, since it'll almost certainly also perform whatever initialisation the driver is currently missing out on. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.

I should have mentioned; you can probably also avoid it by letting your BIOS give the USB controller an IRQ, since it'll almost certainly also perform whatever initialisation the driver is currently missing out on. Right, that is what I did once I realized that this particular commit was the culprit. The commit isn't (really) the culprit; it's just exposed a bug in the USB chipset driver in question. (I'm mostly just making this point so that other people don't go blaming 'correct' PCI behaviour for their problems 8). -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
