What are the thoughts on using 4KB kernel stacks on dom0's and domU's.

Regards,

I've used 4k kernel stacks on xen with no problems.

Appears that 4k stacks on recent changeset's is the root of my problem
bringing snmp guests on line. I switched to 8k kernel stacks and now I
have no more problem bringing up smp guests.

Is testing with 4k and 8k stacks part of the test suite?

I may be being ignorant here (very likely, hehe), but the changes to irq
handling must have some kind of ramification.

Regards,
Ted

Not currently, but since they're becoming default on 2.6.13 we'll update
our configs acordingly.

That's not the first place I'd look...
