Subject: Hard locks under high interrupt load?
Date: Fri, 27 Feb 2004 10:55:51 +0000 [thread overview]
Message-ID: <403F2237.6080505@dcrdev.demon.co.uk> (raw)
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.
