java / futex / signal / 2.6 crash
 

I am running RHEL4 beta-2 on an ASUS NCCH-DL mother board, although I got similar behavior from Mandrake 10.1 on the same hardware.

The machine seems stable, and will happily build the linux kernel over and over in a loop. But, when I use ant to build a fairly large and complicated java project the machine always crashes with a kernel panic just as ant is finishing the build. I have tried with both the SMP and non-SMP .configs from RedHat, as well as a bunch of other configurations. All with similar behavior.

Are there know issues with ant / java / futex's on the 2.6 kernels?

Hardware:
Assus NCCH-DL motherboard, dual 3.2ghz / 800 mhz / 1mb L2 cache cpus
2 gb RAM

Western Digital Raptor 36.7GB 10,000RPM SATA boot disk via on board controller

The crashes all look similar to this:

You could use ksymoops and run a backtrace on that kernel oops. You can get ksymoops here http://directory.fsf.org/devel/debug/ksymoops.html

ksymoops really doesn't give any additional information. ksymoops 2.4.9 doesn't seem to like 2.6 /pro/kallsyms format much.


ksymoops 2.4.9 on i686 2.6.9-prepsmp-ksyms. Options used
-V (specified)
-k /proc/kallsyms (specified)
-l /proc/modules (default)
-o /lib/modules/2.6.9-prepsmp-ksyms/ (default)
-m /boot/System.map (specified)

Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a valid ksym
s file?
No modules in ksyms, skipping objects
