lockup on USB event kernel 2.4.20
Quoted 6 lines
My SO's computer works fine under redhat 8 which runs on a 2.4.18 kernel, however on redhat 9 with a 2.4.20 kernel it locks up. Also, redhat upgraded their kernel to 2.4.20 for rh 8 as well and I saw the same behavior.

Everything works fine until she moves her mouse which is connected to the USB, that locks the system.
Is this a known problem? Any idea how I can debug it?
Thanks

Hi,
Is your controler a UHCI one ?
If yes, try to connect your mouse via a hub if it's directly connected to your computer.
There seem to be an issue with (rare) devices connected directly to UHCI controlers.
I can easily lock UHCI based computers with an ATMEL Wifi device this way.
Regards.

Appears to be using the OHCI driver, so no.

Tried it anyway, no joy.
Any other ideas? Something I could debug would be good. There's a definate correlation between moving the mouse and locking up the machine. Presumably it is missing an interrupt or something like that.
