Default Re: Geforce 8200 users, I need your help with finding usb hanging issue

@laryllan thank you for response. Which CPU do you use? Athlon/Phenom? How many cores do you have on your CPU?

The usb ohci hanging bug is not Nvidia GPU drive related. I'm sure. It is happening even if Nvidia GPU driver is not installed at all. This bug is in:
-usb ohci_hcd driver which comes with kernel sources or
-irq handling driver/apic which comes with kernel sources or
-mainboard bios or
-kernel configuration.
I'm also curious if it is multicore cpu problem.

That is why I'm asking other users with other mainboards, linux distros, kernel versions.

I tried acpi=force irqpoll. System works terrible slow.
Try noapic or acpi=noirq - they do not slowdown system so much.
Let me know if this fixed problem for you. It works for me.
I still try to learn what is wrong because I would like to use my Linux without noapic or acpi=noirq workarounds.

If you would like to learn more about problem I encounter here is bugzilla:

I'm curious if you have exactly the same problems.

WinXP SP3 works perfect with USB 1.1 so this must be bios or Linux software bug.
