crash city this morning

crash city this morning

[Gene Heskett]

Greetings;

While running 2.6.7-mm6, my mouse usb has now powered itself down 2 
times, requireing a reboot to recover, and this last time I rebooted 
to 2.6.7 plain, but have had at least 3 pieces of kde do an exit 
since doing so.

>From my messages log, the second time the mouse died:

This didn't restart the mouse;

Is this related?

---------------
at which point I rebooted to 2.6.7, reset my XF86Config to use the 
old, known stable nv driver, but when startx was run, I got crash 
notices from several pieces of kde, and a ctl+d to end a shell just 
made another crash notice.  Signal 11's, all of them.

Please retest without the nvidia driver, then include
linux-usb-devel@lists.sourceforge.net in the bug report.
