hi, Cijomel
    Why is this bug created under the Power management?
    Do you mean that this issue happens after suspend/resuming?
    Please attach the output of dmesg after the issue happens.
    IMO this is a bluetooth bug rather than a power management bug.
    Thanks.

Comment 2 Zhang Rui 2009-10-15 07:52:51 UTC

does the problem still exists in the latest kernel?

Comment 3 Cijoml Cijomlovic Cijomlov 2009-10-15 16:58:44 UTC

yes at least for me

2.6.32:

Restarting tasks ...
hcid[12313]: segfault at 7 ip b756de93 sp bfa05294 error 4 in libc-2.7.so[b74ff000+155000]
done.

Comment 5 Len Brown 2011-01-18 06:19:09 UTC

is this still a problem in the latest 2.6.32.stable,
and in the latest stable release -- 2.6.37?

Comment 6 Zhang Rui 2011-04-19 07:45:04 UTC

bug closed as there is no response from the bug reporter.
please re-open it if the problem still exists in the latest upstream kernel.
