Distribution: RedHat Linux 9 Hardware Environment: Compaq Evo N610c Software Environment: Problem Description: I use a Microsoft USB mouse with my laptop which had no problems at all with 2.4 all through 2.6.0-test2-mm2. As of 2.6.0-test2-mm4, the mouse freezes and I have remove the hid driver and reload it to get it back. It may work for 2 minutes, 20 minutes, maybe a bit longer (but not much), and it will freeze again. I have to constantly remove hid and reload it. Here is dmesg output after a lockup: drivers/usb/core/usb.c: deregistering driver hiddev drivers/usb/core/usb.c: deregistering driver hid ohci-hcd 0000:02:0e.0: shutdown urb efb54b00 pipe 40408380 ep1in-intr usb 1-2: hcd_unlink_urb efb54b00 fail -22 usb 1-2: hcd_unlink_urb efb54980 fail -22 usb 1-2: hcd_unlink_urb efb54b00 fail -22 drivers/usb/core/usb.c: registered new driver hiddev hid 1-2:0: usb_probe_interface hid 1-2:0: usb_probe_interface - got id input: USB HID v1.00 Mouse [Microsoft Microsoft 3-Button Mouse with IntelliEye?] on usb-0000:02:0e.0-2 drivers/usb/core/usb.c: registered new driver hid drivers/usb/input/hid-core.c: v2.0:USB HID core driver Steps to reproduce: Build 2.6.0-test3-mm2, use the USB mouse as normal.

Do you have problems using 2.6.0-test3 (no -mm)?
Just tested with stock 2.6.0-test3 (used the same .config) and the problem persists. I think my next test is to try with 2.6.0-test2-mm3 to see if it occurs there and if so try to isolate which patch is the culprit.
2.6.0-test2-mm3 also exhibits this problem so it seems it's something that was added at that point. It may be something that was added in one of Linus' BK snapshots. I will try and isolate further.
Ok, took it down to stock 2.6.0-test2 and added the linus.patch from 2.6.0-test2-mm3. Problem exists. In fact, it's even a bit worse in that it seems to kill the local ps2 mouse as well. Next step is to try tracking down what patch in that set is causing the problems.
Interestingly enough, 2.6.0-test4 seems to be working fine for me. I'm certainly keeping an eye on it, but I think this bug can be closed.
