I'm having the exact same problems on my ThinkPad 390X. Sometimes it
freezes several times a day with the exact same symptoms. RedHat 6.2
worked fine on this laptop. The problems started with 7.1 which uses
XFree86 4.0, and it didn't get better with 7.2 (XFree86 4.1).
What makes it even worse is that after a warm reboot, the screen and
keyboard locks up again as soon as gdm gets started (Numlock doesn't work
etc.). So I always have to turn off the power to get the laptop working
again.
