Hi,
HP has just give out F17 Bios. It makes speedstepping_centrino work
again, but it fails to get the processor beyond 1.33Ghz.
[EMAIL PROTECTED]:~# cat /var/lib/acpi-support/*-*
68YAF Ver. F.17
Hewlett-Packard
HP Compaq nx9420 (ES444ET#ABD)
F.17
Interessting anomalie:
[EMAIL PROTECTED]:~# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
1833000
[EMAIL PROTECTED]:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1333000
[EMAIL PROTECTED]:~# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
> /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
[EMAIL PROTECTED]:~# 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:

analyzing CPU 0:
driver: centrino
CPUs which need to switch frequency at the same time: 0
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
current policy: frequency should be within 1000 MHz and 1.33 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.33 GHz (asserted by call to hardware).
analyzing CPU 1:
driver: centrino
CPUs which need to switch frequency at the same time: 1
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
current policy: frequency should be within 1000 MHz and 1.33 GHz.
The governor "ondemand" may decide which speed to use

so long,
