Comment 5 for bug 63439

Hi,

HP has just give out F17 Bios. It makes speedstepping_centrino work again, but it fails to get the processor beyond 1.33Ghz.

root@mephtop:~# cat /var/lib/acpi-support/*-*
68YAF Ver. F.17
Hewlett-Packard
HP Compaq nx9420 (ES444ET#ABD)
F.17

Interessting anomalie:

root@mephtop:~# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
1833000
root@mephtop:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1333000
root@mephtop:~# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
root@mephtop:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1333000

.... which means, that even if i manually try to put the scaling_max up to what the cpu would be capable off - it simply doesn't allow setting the max-scaling freq up to 1.8ghz.

strange, too:

  hardware limits: 1000 MHz - 1.83 GHz
  available frequency steps: 1.83 GHz, 1.33 GHz, 1000 MHz
  available cpufreq governors: userspace, powersave, ondemand, conservative, performance
