Hard lockups - AGP not guilty
I've been experiencing the pleasure of hard lockups on a 2.2GHz SMP Xeon system, with a GF4 PCI card. These lockups occur apparently at random, whilst carrying out normal activities (not running OpenGL applications). Obviously, the usual NvAgp=0 is not going to work, as there is no AGP slot on the board.
The kernel is a vanilla 2.4.19, which appears to have AMD's speculative cacheing patch in it (from reading the appropriate setup.c file).
Can anyone suggest the cause and a possible solution?
