We're still seeing this occasionally, even with 'cpuinfo' added to Xen
args. Serial console stops responding during Xen booting - every time
in the exact same place:
(XEN) CPU9: Intel(R) Xeon(R) CPU L5520 @ 2.27GHz stepping 05
(XEN) CPU 10
The machine continues to boot and becomes available via network, however
nothing I do from then on can get serial to start working again.
Control-AAA, sending massive amounts to /dev/console, etc. If I issue
the reboot command via dom0 something will tickle Xen and a page or two
of buffered OLD data will flush out the serial before the machine
reboots, which is interesting.
In this state hvc_console receives no interrupts. When not in this
state hvc_console seems to get interrupts occasionally. Not sure of its
significance.
I still have a box in this state if anyone has ideas to try.
