Description James Morris 2006-03-17 10:21:18 EST
Serial console works, but is ouput only.
Comment 1 James Morris 2006-03-17 16:34:13 EST
Looks like it's being caused or triggered by ACPI PNP.  As a temporary
workaround, use pnpacpi=off on the kernel command line (unless you actually need
it, of course).
Comment 2 Stephen Tweedie 2006-03-17 16:56:38 EST
Nice catch --- with pnpacpi=off, I can run a xen0 kernel and still capture
serial console from another box.
Comment 3 James Morris 2006-03-17 17:51:19 EST
I've reproduced this problem in xen-unstable, so it looks like an upstream bug.
Comment 4 James Morris 2006-06-02 00:14:08 EDT
This should have been resolved with the upstream fix.
