In 2.6.9 (it works just fine too, problem happens with 2.6.10 and up only), there's no such parameter in drivers/pci/quirks.c. Hmm.
Any chance the order of module loading changed between the two versions? I see you have 'psmouse' as a module. If i8042 (and psmouse) are loaded after uhci-hcd (or ohci-hcd), the problem will disappear, too.
Yes, the prob disappears if usb controller driver is loaded before the mouse driver. Obviously I didn't know USB is "involved" here so I never looked at the problem from this point of view before. Now when I looked at it, I see I have uhci-hcd driver being loaded in my 2.6.9 initrd, before mouse (I removed it after as it wasn't needed). I also tried loading 2.6.9 without uhci-hcd but with USB keyboard/mouse enabled in BIOS - the mouse is flaky too, similar to 2.6.10 behaviour.
Interesting. I was looking at the difference in input subsystem between 2.6.9 and 2.6.10 -- obviously there's nothing relevant here! ;)
So is this a bios/mobo problem,
Yes.
Never had any single problem with this hardware so far. But.. uh-oh. Well.. it's only 2.6 kernel that encounters problem with it for now, so it must be the kernel... ;)
or can it be solved in kernel somehow?
We could have usb-handoff by default.
What's the consequences of this? If it does not hurt (does it?), why not to enable it? And if it does not hurt, I can enable it in our default netboot image as well.. if not to see whenever all our machines will work ok with this parameter.
Thank you very much - this mysterious problem.. I was trying to find the solution for quite some time before posting to LKML, without any success, and the solution was already here! ;)
