I also get a problem specific to host 2.6.16 kernels, but that's when I run
x64 guests on x64 2.6.16 hosts (x86 32-bit guests work normally); I've not
tested 32-bit 2.6.16 hosts.
The error message is different. However, I can't exclude there is the same
root cause acting in a different way, but I've now debugged this a bit and
this seems unlikely.
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Warning: unable to open an initial console.
Kernel panic - not syncing: handle_trap - failed to wait at end of syscall,
errno = 0, status = 2943

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
