[Bug 1176577] Re: [HP Compaq dc7700 Small Form Factor PC] mei unexpected reset in kernel 3.8
Sigh (or in Bavarian actually, fittingly "mei" ;-)), this same bug since
12.04 seems back with the Ubuntu 14.04 LTS, stopping the installer
(which loops slides infinitely without message nor progress) after it
has mounted the /-to-be below /tmp to copy from USB.
See also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1196155
(referenced in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203520) and
http://askubuntu.com/questions/419853/mei-me-unexpected-reset - hope
we'll get rid of it much faster this time around, since the HP 7x00 CMTs
and Dell 7xx Optiplexes are quite likely candidates to be made LTS
machines (so how does this keep slipping into releases?).
How (and if, precisely when?) could one easily blacklist mei (and
mei_me, if need be) when booting a LiveCD?

[HP Compaq dc7700 Small Form Factor PC] mei unexpected reset in kernel
3.8

Bug description:
Right after upgrading kernel from 3.5 to 3.8 (Ubuntu 13.04), the
syslog got flooded by a large number of such messages:
(cut)
May 5 15:33:15 compaq-aldo kernel: [ 205.064042] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
May 5 15:33:21 compaq-aldo kernel: [ 211.076029] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
May 5 15:33:27 compaq-aldo kernel: [ 217.088035] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
May 5 15:33:33 compaq-aldo kernel: [ 223.100039] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
May 5 15:33:39 compaq-aldo kernel: [ 229.112045] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
(cut)
This was associated by non reliable ethernet functionality, i.e.
transfer of large files from my Ubuntu box to a local NAS connected
via ethernet got hanging with no other apparent errors or diagnostics:
nautilus copy just stopped transferring data, leaving the copy window
there with the progress bar stopped.
I tried to reboot, but this behaviour is perfectly reproducible.
This is one of the first syslog lines got from that kernel:
May 5 15:30:15 compaq-aldo kernel: [ 0.000000] Linux version
3.8.0-19-generic (buildd@roseapple) (gcc version 4.7.3 (Ubuntu/Linaro
4.7.3-1ubuntu1) ) #30-Ubuntu SMP Wed May 1 16:36:13 UTC 2013 (Ubuntu
3.8.0-19.30-generic 3.8.8)
I attach the whole syslog from boot of that kernel.
On the same box, launching a previsous kernel (3.5) works flawlessly.
For the time being, I removed 3.8 kernel from my box, now running 3.5.
Kind regards
Aldo
