There's a new bug though, but it looks nicer than the original ugly bug!. The new bug does *not* appear in mainline with the same patch. It's a panic, but this time on the _guest_ side (which is the same host's kernel). [ 0.023996] CPU: Intel(R) Pentium(R) M processor 1500MHz stepping 05 [ 0.023996] Kernel panic - not syncing: Kernel compiled for Pentium+, requires TSC feature!

It seems lguest is very sensitive to x86 tree changes. Could it be included in a sort of automatic guest-boot testing, please ?
