dom0 boot lockup using async serial console
Last modified: 2007-11-30 17:11:29 EST
Description of problem:
Using serial console output from dom0:
kernel xen.gz com1=38400,8n1
module vmlinuz... console=ttyS0
results in a hang at bootup.
Adding "sync_console" to the xen.gz line cures it.
Version-Release number of selected component (if applicable):
Observed in many rawhide releases; still needs to be confirmed with 1.2080.
Fixed by the APIC irq ack changes a month or so ago; working fine in current
