Hi Henrik,

What Bluetooth host controller are you using?
Which part are you testing (Magic TP or mouse)?

I've been trying to test these patches on a Magic Trackpad using two
computers, with two different ath3k parts.
On one of them, the BT communication freezes immediately after the
first report with 3 fingers.
On the other, it reports all 10 fingers, just fine.

The only difference I can tell is the version of the Atheros Bluetooth chip.

What does your freeze look like?
