| Doc Text: |
Cause:
seabios tries to use the tsc for timekeeping, with a simple calibration loop.
Consequence:
on a busy host the calibration can be wrong by orders of magnitude, resulting in timeouts being way too short, leading to boot failures.
Fix:
use (fixed frequency) pmtimer for timekeeping.
Result:
timeouts are working correctly under all circumstances.

updated bios binary
Oops, no bios update, I through I did that already.
The backported patch hasn't been merged into the rhel6 package yet.
Attached is a bios binary with the patch applied for testing. Pass
the binary to qemu.kvm using the -bios switch.
With the updated bios the 'black screen' failures should go away.
