I have the same symptoms and i am unable to find the source of them. It happens in the following situations: - X is running - some kind of heavy-graphics-resource-consumption is happening, like: twm is configured to opaque-move AND i am dragging the netscape-window AND some other action takes place so that the graphical refresh is delayed. then my X-session gets kicked completly. This is the best i was able to get to. When this drama first started, not only my whole X-session got kicked, but the machine immediately rebooted on this (no panic-message, no nothing). What i did to make the symptoms less catastrophic: - probably change the slot-order of some PCI-cards (i had to) - set the PCI-interrupt of the graphics-board to "N/A" (if it is a PCI-card) - check the termination of your SCSI-bus. Check for TERM-POWER suppliers on your SCSI-bus and switch them off. The only device that should need to supply term-power to the SCSI-bus is the SCSI-controller. - turn off any graphics-resources-intesive features in your window-manager (opaque-move, ...) - i've found interrupts to cause the worst cases in this drama: while my ISDN-card is actively transferring packets and therefor issuing many interrupts and i opaque-move the netscape-window, in most cases this causes a crash. It must be said here, that my ISDN-card (AVM-Fritz!-ISA) generates about 200 interrupts/s when there is no activity on the ISDN-bus. If there is activity, this number gets much higher. So the source of all that evil is probably a combination of the following: - bad graphics-card - power-problem on the SCSI-bus - bad interrupt-controller - bad ISDN-card (generating >= 200 interrupts/s) - bad RAM The min. number of interrupts i get on my system when just running X without doing anything (not even moving the mouse) is 270 (while watching xpermon++). What is your's ?
