Package: linux-2.6
Version: 2.6.22-2
Severity: normal

        Hi,

 Summary: echo 0 > /proc/sys/vm/vdso_enabled hangs my kernel.

 Since some months, I get unusable backtraces from gdb; I was pointed at
 an OpenSuse bug at:
    <https://bugzilla.novell.com/show_bug.cgi?id=258433>
 which suggests disabling VDSO.  My value of /proc/sys/vm/vdso_enabled
 is 2 before I try, and the system hangs shortly after I echo 0 in that
 tunable.

 The important issue I'd like to see fixed is this backtrace issue, but
 I'm reporting this crash as I think the kernel shouldn't crash and
 because I'm using this tunable to diagnose the backtrace issue.

 I'll use a kernel command line parameter in the mean time.

   Bye,

Both problems are fixed, vdso disable does not longer hang and the vdso
access is allowed.
