The second scan times out on Oneiric on both my computers. By turning Bluetooth on and off, I can scan once again. When testing my iMac on Natty, I can scan as many times as I like without timing out.

I first discovered the bug when trying simplescan.c http://people.csail.mit.edu/albert/bluez-intro/c404.html#bzi-choosing

Hi,

this is kernel issue and already fixed in upstream kernel (3.1-rc8)
Please see

Is there any chance that the patch will be back ported to Oneiric?

It would be a big shame if Oneiric shipped with broken Bluetooth.

[Chris (ccouzens)]

I've not had this issue recently. Has it been patched?

[Konrad Zapałowicz (kzapalowicz)]

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
