The Linux changelog people seem a bit comfused...
I just received Linux 4.8.0-31.33,
and ITS changlog says:
" * Yakkety update to v4.8.11 stable release (LP: #1645421)
...
- Linux 4.8.11
* Yakkety update to 4.8.7 stable release (LP: #1642606)
...
- usb: increase ohci watchdog delay to 275 msec
...
- Linux 4.8.7
"
It lists changes for 4.8.0-31.33, ;.4.8.0-30.32, 4.8.0-28.30 and earlier,
but NOT for 4.8.0-29.31 , which was where issues for 4.8.11 were shown as fixed
before (see my comment #44) And the changelog for 4.8.0-30.32 was very short -
one item.
If it truly was not actually fixed until today, then the one time I
tried to print and succeeded (after installing 4.8.0-29.31) must somehow
have been a fluke...

Title:
specific USB devices disconnect and don't reconnect
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Yakkety:
In Progress
Bug description:
2 USB ports randomly disconnect and don't reconnect (it's always the
same two), and in dmesg all I get is
"
[ 1276.916458] ohci-pci 0000:00:12.0: HcDoneHead not written back; disabled
[ 1276.916467] ohci-pci 0000:00:12.0: HC died; cleaning up
[ 1276.916553] usb 3-1: USB disconnect, device number 2
[ 1277.017302] usb 3-2: USB disconnect, device number 3
"
This only started happening when Yakkety went to the 4.8 branch, with 4.7
branch this doesn't occur, hence the bug report since it's unlikely that a
hardware failure will only stick to one OS and one branch of the kernel for
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested
that in the past couple of days)
