Hi,
I have an annoying problem with my PC : the keyboard locks up very often.
Hardware : Dell laptop, model Inspiron 5000e, BIOS 06, CPU 600 MHz, 256 Mb
ram, 30 Gb IDE disk, 1600x1200 ATI graphic board, Logitech Wheelmouse
optical USB, model M-BD58 (a true Logitech with color logo, no
OEM-version).
Software : Mandrake 8.0, with a good bunch of official updates and a
self-compiled kernel from kernel.org mirror, without any patch, GPM *not*
running, XFree86-4.0.3-7mdk
first, the situation without problem :
- mouse on PS2 port with USB-to-PS2 Logitech adapter
- XF86Config-4 goes to /dev/psaux for the mouse
now the problematic configuration :
- mouse connected directly to USB port
- XF86Config-4 goes to /dev/input/mice
- nothing else on USB bus
in this config, after working for a while (from 3 min to 2 hours), the
keyboard suddenly locks completely. It's not an application issue, as I
can remotely login and kill X, the lock remain. The only way to get out is
to suspend and resume. I do this using the keyboard key combination. I
suppose therefore that the Fn-Suspend goes to BIOS, which trigger the
suspend. Somewhere in the "upper" layer, my key presses are lost.
In the same config, a lot of keypresses are lost. I evaluate the ratio
loss/good at 1-2%. This key loss problem is not at all present in the
non-USB config.
I definitely would like to get my mouse working on USB, because it's the
only mode where I can get the wheel to work using IMPS/2 protocol in
XF86Config-4.
The problem wasn't present on this laptop with 2.2.x. I think the problem
appeared with 2.4, but I'm not very sure, as I haven't be able to test
this for a long time (because APM wasn't working and each kbd lock needed
a cold boot). Now that I can play with it without enduring 30Gb of mke2fs,
I really would like your help to sort it out.
I'm ready to test all sort of patches and report back to LK, as soon as
you don't ask me to reformat my drive :-)
I have collected some info below, let me know if you need more.
