Re: cpu speed problem



Hi Andy
down /proc/acpi i see (between others)

[myuser myhost ~]$



i assime the freeze/resume sequences are at the initiation of a suspend and a resume sequence respectively


see now actually the temparature has gone up farer:
[myuser myhost ~]$ cat /proc/acpi/thermal_zone/THM/temperature
temperature:             58 C
[myuser myhost ~]$



many thanks for your ideas and help

Did you look into which process was eating the extra CPU?

-Andy

Could the extra CPU usage be because the CPU is running so much
slower that it requires a higher CPU load to do the same tasks?

You're quite right, it can easily be that.

Is there anything down /proc/acpi any more on this machine then, in case
it no longer is able to start ACPI?

Anything interesting in

dmesg | grep ACPI

-Andy
