Public bug reported:

When booting the x86 kernel (touch x86 emulator):
[    0.000000] Fast TSC calibration failed
[    0.000000] TSC: Unable to calibrate against PIT
[    0.000000] TSC: No reference (HPET/PMTIMER) available
[    0.000000] Marking TSC unstable due to could not calculate TSC khz

Which then causes cpu MHz to be 0 at /proc/cpuinfo:
phablet@ubuntu-phablet:~$ cat /proc/cpuinfo 
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 3
model name      : Pentium II (Klamath)
stepping        : 3
microcode       : 0x1
cpu MHz         : 0.000

This doesn't happen all the time, so it might be a combination of qemu +
goldfish.
