Latest kernel update causes bluetooth issues

The latest kernel that came out (if I recall it is 2.6.39.3-1) has created some issues for me with bluetooth radio on my Thinkpad X61.  Whenever my comptuer boots up, bluetooth is now disabled.  Enabling it causes the icon in the notification area to disappear completely.

From boot messages:

giladh@tharch ~ $ dmesg | grep bluetooth
[    6.409840] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked
[   73.809657] bluetoothd[1469]: segfault at 30303030 ip b76987bd sp bf8a34d0 error 4 in libglib-2.0.so.0.2800.8[b763b000+ed000]

From rc.conf:

# DAEMONS
DAEMONS=(syslog-ng dbus networkmanager ntpd rpcbind nfs-common nfs-server @netfs crond cups sshd alsa samba osspd laptop-mode sensors nginx bluetooth !postfix !amavisd !clamav !spamd)

Manually restarting the bluetooth daemon solves the problem until next reboot.

I know I should file a bug for this but:

1. I don't know how to
2. I want to know if anyone else has the same issue

Thanks,

Archieman

Re: Latest kernel update causes bluetooth issues

I'm having the same problem. It seems there is also already a bug in the tracker: FS25088. I downgraded bluez to version 4.94-1 for now, which seems to work.

Re: Latest kernel update causes bluetooth issues

I currently have the latest bluez version (4.96) on my x61t and it didn't occur to me to downgrade when the version was still at 4.95.

Now, when I downgrade bluez, nothing changes.
Bluetooth manager in XFCE doesn't run on startup and even after I manually run it, it cannot do anything. It doesn't recognize the BT hardware and that's just it. Even the BT LED doesn't light up as it used to when booting.

I've tried restarting the daemon and modules - no effect.

Does anyone have any idea as how to correct this anomaly? Do I have to downgrade anything else? Me thinks it's waaay better to ask before downgrading a bunch of dependencies, because I managed to completely screw up my system once by downgrading things I shouldn't have.

I have seen a bluetooth kernel patch somewhere a few weeks ago but I absolutely couldn't find it any more the next day.

Any ideas?

Re: Latest kernel update causes bluetooth issues

Hoooly cow!

I had my hardware radio switch turned off this while time. Oh God!

Well, bluetooth working fine for me now.

Note:
Don't know though whether the original thread issue has been resolved though.
Marking as resolved or not?
