Onboard bluetooth chips are known to get flakey and fail to enumerate until power cycled, which is tricky if they run off a standby rai= l.

The delay is a consequence of missing interrupts *and* having some USB devi= ce connected. Your case is similar to the other one. Sorry about the wrong instructions. Indeed, tar doesn't work with debugfs. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
