What version of the kernel and patch-set did you test against?

Over the last month I've tried *EVERYTHING* I can lay my hands on and can still cause a crash VERY easily!

So I am guessing that you are having memory corruption from some source.
Either bad ram or a bad module.


On my DELL 1850 dual-core dual-Xeon system I did have a flaky DIMM which cause a few correctable ECC errors, but that has been replaced and still the same. My other test systems are (multiple) DELL 1425 dual-Xeon machines [2.8 or 3.0 GHz chips].


I'm off on vacation for a week, so I won't be able to follow up.


Have a good one...
