Hi,
Since sometime in December two systems we have on site using P4 HT (one
Dell 2650 and one Dell 4600, both dual CPU, both ht/mce capable) have been
locking up without any kernel output and without sysrq keys working (the
keyboard is locked solid). I've dropped the 4600 back to 2.4.19 but the
2650, not yet in production, is still running 2.4.20 to troubleshoot the
problem...
Using nmi_watchdog I've managed to get a stack track and ran ksymoops over
it (attached). Also attached is the .config file used to build the kernel.
The lockup is reproducable, although this is the first time I've managed
to get any feedback from the kernel on the problem. 2.4.19 with the
same patches, but without tg3, does not lockup...
Thanks in advance for any help that can be given.
Here's more information about the system the oops was captured on:
(kernel compiler)
bash# gcc -v
