Bug#615964: oprofile: `Error: counter 0 not available` with Linux kernel 2.6.37

[Paul Menzel]

Subject: oprofile: With 2.6.37 Error: counter 0 not available
Package: oprofile
Version: 0.9.6-1.1
Severity: important

Dear Debian folks,


using `linux-image-2.6.37-2-{amd64,686}` I get the following error.

        $ sudo opcontrol --start
        Using default event: CPU_CLK_UNHALTED:100000:0:1:1
        Error: counter 0 not available

Using `linux-image-2.6.32-5-{amd64,686}` OProfile works fine.

Here is the verbose output.

        $ sudo opcontrol --start-daemon --verbose
        Parameters used:

Running `strace`

        $ sudo strace opcontrol --start-daemon
        […]
        stat64("/dev/oprofile/0", 0xff874828)   = -1 ENOENT (No such file or 
directory)
        rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
        write(1, "Error: counter 0 not available", 30Error: counter 0 not 
available) = 30
        rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
        stat64("/proc/sys/kernel/nmi_watchdog", 0xff874628) = -1 ENOENT (No 
such file or directory)
        rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
        rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
        exit_group(1)                           = ?

it looks like that certain devices are not available. The module seems to load 
fine according to the output of `dmesg`.

        [  812.337393] oprofile: using NMI interrupt.

Please reassign this report to the appropriate package. Is this a Linux kernel 
issues? Although I would be surprised because I did not find a lot of reports 
on the WWW.

Just for your interest, I can reproduce that on two different machines.


Thanks,

Paul
