| |
I'm having zero success in getting 2.6.3 stable under interrupt load. I can kill my machine in a variety of fashions all of which appear, to my naive eye, related to interrupt load:
(1) LAN traffic via E1000 card (X is not running) (2) Running X for more than a few minutes - starting up a couple of applications whilst performing some disk-based activity (such as a compile) usually seems to do the trick.
(2) is worth a little more examination. I have an NVIDIA card (I can hear you all groan) *but* I get the same results with the XFree driver *or* the proprietary NVIDIA driver.
Disabling IO-APIC usage seems to resolve the problem.
Machine is a dual Xeon, Tyan S2665 (E7505 chipset) with an MPT-Fusion SCSI controller.
2.4.26-pre1 and various other 2.4 kernels give me no problems at all. I really want to switch my machines over to 2.6 but I can't whilst this problem persists.
Cheers,
Dan.
