[BUG] JVM crashes with 2.6.9-rc2

[BUG] JVM crashes with 2.6.9-rc2

[Pekka Enberg]

Hi,

Sun JVM 1.4.2_06 crashes with Linux 2.6.9-rc2 and later on i386 when I
start Eclipse. The JVM dies a horrible death claiming internal error.  I
noticed similar problem with Blackdown JDK 1.4.2_rc1 as well.  I have
put a full strace of the run here [1].

I also tested 2.6.7, 2.6.8.1, and 2.6.9-rc1 and they all work fine.
Reverting Roland's i386 syscall tracing patch [2] from 2.6.9-rc2 makes
the problem go away for me.

Could you test
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/snapshots/old/patch-2.6.9-rc4-bk3.gz?

That's peculiar.  Are you sure about that?

Hmm.. The strace is pretty nondescript, because the abort happens in some 
other thread than the initial one. That said:

That's just _weird_. For one, Roland's patch should only matter when 
tracing or auditing. For another, it shouldn't matter then either ;)

Can you double-check your test setup (and the kernel you tested) just 
because I don't see how that patch can matter.

I tested again and I now get the crash with _all_ of the above kernels
so it's definitely not the patch.  Sorry about that.  I'll run memtest86
tomorrow to see if my hardware is broken.

In case anyone is interested, here's the error message:

Sorry, this is probably not a kernel bug.

My test case was slightly different for the first and second run which
is why I got varying results.  I can reproduce the crash now with _all_
recent 2.6 kernels so the bug is likely somewhere else.  The JVM crashes
at different locations depending on the kernel version which is why I
thought the problem was in the kernel in the first place.

Thanks a lot for the help and sorry for the noise.
