I don't know about the kernel, but there's a known bug with 4.34 that can make
bluetoothd crash when unpluging/repluging adapters. This was fixed in git
already several days ago with commit 457056310229911e820357470ee8fb30c82516da
("Fix org.bluez.Audio unregistration") so you might want to try if it helps.
I just did a git pull to get the latest bluez and bluetoothd still gets a
Segmentation fault when I use my Linksys USBBT100 bluetooth adapter.
I used to use my USBBT100 with bluez 3. I was already using bluez 4 when
I bought my Belkin F8T017 bluetooth adapter.
I start bluetoothd without the USBBT100. When I plug it in the interface is down.
When I do hciconfig hci0 up the CPU usage goes up to 100% for 8 seconds and then
bluetoothd gets a segmentation fault.
If the USBBT100 is already plugged in when I start bluetoothd then bluetoothd crashes
6.3 seconds later having used 5.9 seconds of CPU time.
Neither valgrind nor gdb show anything of any interest.
I have installed bluez-4.36 and it has the same problem. I have a 2.6.30-rc2 kernel.
My Belkin F8T017 bluetooth adapter works fine.
strace -f on bluetoothd shows that it is looping as shown below.

I guess that if you have read this far then you have found the solution as I did
mv /var/lib/bluetooth/00:0C:41:E1:FF:30/config /var/lib/bluetooth/00:0C:41:E1:FF:30/config.old
/var/lib/bluetooth/00:0C:41:E1:FF:30/config was recreated containing
: root; cat /var/lib/bluetooth/00:0C:41:E1:FF:30/config
class 0x480104
I guess that this is why my USBBT100 never (?) worked with bluez.
