Bug Description

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.

Changed in linux-goldfish (Ubuntu):
