Bug Description
Binary package hint: linux-image-
I upgraded from dapper to edgy. The files in the directory /sys/devices/
$ ls /sys/devices/
crash_notes
$ sudo cat /sys/devices/
1ff68400
In dmesg I see a strange line that might be related to this problem:
[17179625.508000] acpi_cpufreq: Unknown symbol cpu_online_map
It's a centrino laptop (acer travelmate 4650 series (4651)).
As a result of this bug, I can't get cpu frequency scaling working correctly.
To post a comment you must log in.
Same problem here after upgrade!
but I'm using a P 4 -M
cat /sys/devices/ system/ cpu/cpu0/ crash_notes
1fe62800
cat /proc/cpuinfo | grep name
model name : Mobile Intel(R) Pentium(R) 4 - M CPU 1.70GHz
As a workaround I got it working when I added "p4-clockmod" to /etc/modules
With this module loaded everything seems to be ok now in /sys/devices/ system/ cpu/cpu0/
on my system after reboot!
