Bug Description
Binary package hint: byobu
On my PandaBoard (dual core ARM) Byobu shows "2x2.0GHz" as speed.
But CPU is clocked at 1GHz and on ARM there is no entry in /proc/cpuinfo which shows that:
10:16 hrw@panda:~$ cat /proc/cpuinfo
Processor : ARMv7 Processor rev 2 (v7l)
processor : 0
BogoMIPS : 2013.49
processor : 1
BogoMIPS : 1963.08
Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x1
CPU part : 0xc09
CPU revision : 2
Hardware : OMAP4430 Panda Board
Revision : 0020

Hi there,
Thanks for the bug report and /proc/cpuinfo.
So the script tries to use BogoMIPS when there is no specific clock speed specified. Looks like I need to divide that by the number of processors?
Any chance you can collect a couple of /proc/cpuinfo's and attach them to this bug so that I can confirm this hypothesis?
Thanks!
