Description David Hollis 2003-08-13 08:21:46 UTC

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

Steps to reproduce:
Build 2.6.0-test3-mm2, use the USB mouse as normal.

Comment 4 Greg Kroah-Hartman 2003-08-14 09:30:22 UTC

Do you have problems using 2.6.0-test3 (no -mm)?

Comment 5 David Hollis 2003-08-15 11:09:20 UTC

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.

Comment 6 David Hollis 2003-08-16 12:38:18 UTC

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.

Comment 7 David Hollis 2003-08-19 17:45:56 UTC

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.

Comment 8 David Hollis 2003-08-24 06:26:28 UTC

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.
