Description Pavel Machek 2006-01-25 11:52:07 UTC 
Distribution: Debian
Hardware Environment: i386

Steps to reproduce: Suspend to RAM (and I think suspend-to-disk too, will
verify) breaks bluetooth running over CF card.

Problem probably is because CF card is initialized from userland (by
hciattach?), and userland has no idea that we have just suspended. After resume,
I have endless stream of errors in syslog.

...perhaps error handling in bluetooth-over-serial needs some improvements...
Comment 1 Rafael J. Wysocki 2006-09-29 07:14:55 UTC 
Has it been fixed after 2.6.16-rc1?
Comment 2 Rafael J. Wysocki 2006-10-25 10:10:01 UTC 
Due to the lack of response, I assume that the problem has been fixed.  Please
reopen if that's not the case.
