As promised, I tried 2.6.26.3 this morning and didn't have the problem. I will

Nb Although the log had an XFS failure, I think the real issue is the segfaults;
I think XFS is a casuality, not a cause. Th problem almost always results in an
XFS crash at some point - but usually preceded by many segfaults in random binaries.
