Public bug reported:
In trying to build a zoneminder server, I think I stumbled on a kernel
bug. It seems to have snuck in sometime between 16.04 desktop promoted
to server, and 17.04 server promoted to desktop.
The suggestion is that the very popular Nec/Renasas 27xxx2 may need
"quirk" in the kernel.
Timeline:
(Scene 1)
Loaded 16.04 Ubuntu Desktop
Promoted Desktop to Studio
Promoted Desktop to Server
Added Zoneminder
Needed more cams, added Startech PEXUSB3S44V NEC/Renesasa 27XXX2 based card
for more USB channels.
Everything worked quite well. Some errors in ZM but no DMESG as far as I
recall.
(Scene 2)
Wiped the drive.
Loaded 17.04 Server
Now getting messages in DMESG complaining of thousands of errors:
[96415.044917] handle_tx_event: 516 callbacks suppressed
[96415.044924] xhci_hcd 0000:0c:00.0: WARN Successful completion on short TX:
needs XHCI_TRUST_TX_LENGTH quirk?
Messages suggest "quirk" is the solution.
a)Researched usb 3.0 "quirk'
b)Noticed it's really a "thing"
c)Couldn't find recipe for patching kernel for NEC/Renases "quirk" fix.
(Scene 3)
Anecdotes suggest Nec/Renasas firmware is to blame.
a) Kernel indicates 2024 firmaware
b) Startech website has 2026 firmware.
c) VERY IMPORTANT! WindowCentric GUI instructions do not translate between
ASCII and HEX. So if your Startech is on channels 9, 10, 11, and 12 from
perspective of Windows, you must translate into 09, 0A, 0B, and 0C when editing
runfile for effective firmware update of all 4 controllers. Yes, for the 4
channel controller, count them: 4.
d) Firmware updated.
(Scene 4)
Rebooted with new Startech/Nec/Renases 2026 firmware.
SAME OLD PLETHORA OF ERRORS
(Scene 5)
I give up.
It may well be worth noting that there are no errors from DMESG until some
seconds after the first webcam is attached to the Startech.
And I can't overemphasize the fact that I don't think I had any DMESG errors
under Desktop 16.04
I think the file attached represents DMESG immediately before the errors
start going nuts. My theory is that ZM does lazy polls on missing cams
but once it gets 'hold if the cam and sucking data the quirk bug
surfaces.
