Dear all,
I've encountered a problem with powerd which seems to be specific
to ASUS T9400 laptop. Powerd crashes after arbitrary amount of
time saying that its impossible to configure (usually, but not
necessarily) the maximum processor speed:
# powerd -v -p 200
idle time 90%, decreasing clock speed from 787 MHz to 700 MHz
idle time 90%, decreasing clock speed from 787 MHz to 700 MHz
idle time 90%, decreasing clock speed from 612 MHz to 525 MHz
idle time 65%, increasing clock speed from 700 MHz to 900 MHz
idle time 90%, decreasing clock speed from 787 MHz to 700 MHz
idle time 90%, decreasing clock speed from 700 MHz to 612 MHz
idle time 90%, decreasing clock speed from 612 MHz to 525 MHz
idle time 65%, increasing clock speed from 787 MHz to 900 MHz
idle time 65%, increasing clock speed from 787 MHz to 900 MHz
idle time 90%, decreasing clock speed from 612 MHz to 525 MHz
idle time 65%, increasing clock speed from 525 MHz to 700 MHz
idle time 90%, decreasing clock speed from 612 MHz to 525 MHz
idle time 65%, increasing clock speed from 612 MHz to 787 MHz
idle time 90%, decreasing clock speed from 612 MHz to 525 MHz
idle time 65%, increasing clock speed from 612 MHz to 787 MHz
idle time 90%, decreasing clock speed from 700 MHz to 612 MHz
idle time 65%, increasing clock speed from 700 MHz to 900 MHz
powerd: error setting CPU frequency 900: Device not configured
and dmesg shows:
acpi_perf0: Px transition to 900 failed
acpi_perf0: set freq failed, err 6
Interesting thing is it looks like sometimes it succeeds setting
the frequency 900 MHz and sometimes not.
Kernel config and dmesg is below. (BTW, there is also another
problem obvious from the dmesg:
Interrupt storm detected on irq11: cbb0 cbb1+; throttling interrupt
source
wi0: Lucent Technologies WaveLAN/IEEE at port 0xd000-0xd03f irq 11
function 0
however, I will perhaps describe this in another mail).
Thanks,
Petr
