Hi list,
I have a Apple Inc. MacBookPro11,1 (with the most recent 'bios': BIOS
MBP111.88Z.0138.B16.1509081438 09/08/2015).
At the beginning, USB worked normally. After a while (and after newer kernel
versions released by debian?) things started to act strangely. For one, the
you need to try with latest kernel from Linus. Please download v4.6-rc3
from kernel.org, compile and try with that.
I've tried with kernels from 3.16 to v4.6-rc2 updating every few weeks.
Anything special I should watch out for in rc3 that changed since rc2?
nothing special. Just to confirm, can you check that disabling LPM
solves the problem ?

No change what so ever. I also booted a few times to OSX (to install
some updates in hopes there where some bios/efi' updates) and while the
restart 'speed' was good on one reboot, the other 10 or so failed to
reboot quickly. It 'feels' like the xhci controller is in a wrong state
at shutdown and takes a while before it can even boot (reading the EFI
disks etc before bringing up the apple bootloader. Whatever causes it to
boot correctly, I don't know).
I'm happy to try any other patch on top of 4.6-rc3
bios/efi boot takes a very long time (probably due to the same reason I describe
later) just to get to the bootloader/grub. Likley resetting and probing for USB
ports/mass storage. When grub finally pops up, I can use the (internal USB based
keyboard) normally to select a grub entry etc.
Booting the kernel then works reasonably fine, until it loads the xhci module.
It spews some messages in dmesg (taking some 15 seconds) and only then, the
keyboard starts to work again.
which messages ? We need these dmesg messages
As mentioned by Janna, they are at the bugzilla issue number 115741 [0]
(unless you prefer them zipped otherwise they sometimes don't fit).
no, it's okay.
