Well, enter a acpi bug on bugzilla with acpidump output and dmesg attached.
Another interesting thing is shown here:
patrol@arcus:~$ cat /proc/acpi/processor/CPU1/info
processor id: 0
acpi id: 1
bus mastering control: no
power management: no
throttling control: yes
limit interface: yes
patrol@arcus:~$ cat /proc/acpi/processor/CPU2/info
processor id: 1
acpi id: 2
bus mastering control: no
power management: no
throttling control: no
limit interface: no
As I remember, both cores were showing the same things formerly.
The only line referring to CPUs during boot is
ACPI: Processor [CPU1] (supports 8 throttling states)
and CPU2 is not mentioned at all.
The last (but maybe not acpi-related) strange thing is that in /proc/cpuinfo,
CPU1 reports 6403.56 bogomips (as always, approximately twice the clock) and CPU2
8314.32 ones (too much). It's also very suspicious. Formerly the difference was
very small.
Should I provide more info to debug these things, or is it OK ?
With regards, Pavel Troller
