Hi.

I use bluetooth keyboard with Openrc and Bluez.
Since last net-wireless/bluez-5.75 upgrade, bluetooth service crashes on system wake up.
I had created a udev rule for enabling wake up via BT keyboard : 

$ cat /etc/udev/rules.d/70-mouse-keyboard-wakeup.rules 
ACTION=="add" \
, ATTR{product}=="BCM[A-Za-z0-9]*|[A-Za-z -_]*[mM]ouse|[A-Za-z -_]*[kK]eyboard" \
, ATTR{power/wakeup}="enabled"

#, ATTR{idProduct}=="21e8|2510" \
#, ATTR{idVendor}=="0a5c|093a" \

Strangely, my keyboard can still can wake the system after sleep (suspend to RAM) but bluetooth rc-service crashes immediately after...
A rc-service bluetooth restart can solve the problem until next sleep.

Waiting for a solution, I masked package net-wireless/bluez-5.75 and everything work well with bluez-5.72.

Thx for help

I had this issue, and can confirm that upgrading to bluez-5.76-r1 appears to have resolved the issue. I will keep a close eye on it, and report back if this proves not to be the case.

Thx Paul Jewel,

I just tried to replace 5.72 by 5.76-r1 and I confirm it seems to solve the problem too.
Only v.5.75 seems to be impacted by the issue…

To confirm.

Hi.

I reopen this thread as net-wireless/bluez-5.78 seems to push the same issue.
I masked this version in /etc/portage/package.mask, re-emerged bluez (version 5.77) and restarted bluetooth rc-service and it works as expected again.

Anything to correct in v.5.78 ?

What errors are reported when it crashes?

Hi.
After entering suspend to RAM and wake system from keyboard, I have this in dmesg :
