Sorry for the lateness of this reply. I just got around to reading the
messages from the various mailing lists I've subscribed to.
I get this behavior consistently under 2.2.2 when running restore. If I
restore a file I can repeat this 100% of the time. Another way to repeat this
100% of the time is to use GDB and set a breakpoint in a program.
My questions are, is this a VM fix or a PROCFS fix? Do you feel comfortable
enough with the fix to have this merged into -stable by the time that 2.2.6 is
released?
