There is absolutely no reason why delaying bluez from starting should affect S3/S4 or killswitches in any normal case, especially not in a relation with dbus, for which the connection is only established on startup.
There *is* a chance where bluetooth would start and not have dbus available, but in this case it would fail immediately on startup, which does not appear to be the issue at hand. That said, since it's a possibility I have a test patch ready. Please attach a full copy of /var/log/syslog to this bug report so we can see all the messages from bluez and from the kernel bluetooth subsystem. It really seems to me like this is an issue caused by an incomplete initialization of the bluetooth device by the time bluez starts, which is something that really should get fixed in the kernel itself rather than as a workaround in bluez. ** Changed in: bluez (Ubuntu) Status: New => Incomplete ** Changed in: bluez (Ubuntu Precise) Status: New => Incomplete ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: bluez (Ubuntu) Assignee: Canonical Desktop Team (canonical-desktop-team) => Mathieu Trudel-Lapierre (mathieu-tl) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1221618 Title: Bluetooth doesn't work after S3/S4 or after turning bluetooth on/off several times by toggle key Status in Bluez Utilities: New Status in OEM Priority Project: Confirmed Status in OEM Priority Project precise series: Confirmed Status in “bluez” package in Ubuntu: Incomplete Status in “linux” package in Ubuntu: New Status in “bluez” source package in Precise: Incomplete Status in “linux” source package in Precise: New Bug description: After S3/S4 or turning bluetooth on/off several times by toggle key, there are many error messages in dmesg.
