Problems with hp nx9010
Hi all:
I recently bought an hp (compaq) nx9010 and I cannot get it work
correctly under 2.6.0. I realized that the company has updates for the
BIOS and installed the lattest one. However, the ACPI bios seems to be buggy.
2.4 kernels work perfectly, but as the laptop has not apm support and I
haven't installed any acpi patch, the battery and such doesn't work.
OK, but I tried with 2.6.0 (instaled from the debian package
archive), and find some strange things that I really don't know how to
handle. First, this is the /proc/cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Mobile Intel(R) Pentium(R) 4 CPU 3.06GHz
stepping : 9
cpu MHz : 3057.053
cache size : 512 KB
physical id : 0
siblings : 1
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid
bogomips : 3046891.52
What is this strange bogomips value??? Anyway, I see from the
/proc/acpi that there is no fan control, but the processor temperature
meter works OK.
However, the greatest problem of all is that the X-Window seems
to freeze for one or two seconds whenever it decides. It seems that it
is a X-Win problem, as the wireless pcmcia card continues working...
In the freezes, sometimes the last key pressed seems to stay pressed
during these two seconds, and after that, a lot of keystrokes appear.
I have some dmesg logs that are interesting and I cannot
explain, so I would like anybody in this list that knows more than I do
can help me:

Jan 23 23:46:40 d kernel: task migration cache decay timeout: 2 msecs.
First, it says HT is disabled, but I haven't seen any option in the BIOS
to activate it. How do I know if he CPU supports HT?
Anther interesting bit is that one:
Jan 23 23:46:40 d kernel: ACPI: Processor [CPU0] (supports C1 C2)
Jan 23 23:46:40 d kernel: cpufreq: CPU0 - ACPI performance management
activated.Jan 23 23:46:40 d kernel: cpufreq: *P0: 3059 MHz, 20000 mW,
250 uS
Jan 23 23:46:40 d kernel: cpufreq: P1: 1596 MHz, 10000 mW, 250 uS
Jan 23 23:46:40 d kernel: cpufreq: No CPUs supporting ACPI performance
management found.
What does this mean? As far as I see, CPU0 supports two working modes,
P0 and P1, but why does it say that no CPU support ACPI??? I have also
loaded the p4-clockmod module and it works. I can switch between
powersave and performance, but I'm not sure how I can control directly
the two working modes (If I could, I could switch to 1.5GHz when the AC
is off). The AC, battery, etc. modules work, but still the X hangs
regularly for two seconds or so...
Any hints?
Really thanks in advance,
diego
