Just to be clear. This problem is where my system won't resume after s2d

This is really weird. I don't see how xfs mount can affect this at all.
Indeed.
It does :)
How hard does the machine freeze? Can you use sysrq? If so, please
dump sysrq-t.
I suspect there is a problem writing to the consoles...
I recompiled (rc4+patch) with sysrq support, suspended, resumed and tried
sysrq-t but got no output.
I *can* change VTs and see the various login prompts, bitmap messages and the
console messages. Caps/Num lock lights work.
Fearing incompetence I tried sysrq-s sysrq-u sysrq-b and got a reboot so sysrq
is OK.
Any suggestions on how to see more? Or what to try next?
Any other kernel debug options to set?
David
PS Back in a couple of hours...
