Bug#939262: firmware-iwlwifi: Consider update to newest version (20190815)

2019-12-12 Thread Andrew Bettison

See my report in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=934781#30

On my Dell Precision M6400 laptop, the newer iwlwifi 20190815 firmware 
only partly fixes the problem.  The Wi-Fi no longer hangs (great!), but 
Microcode SW errors still occur in periods of high throughput.

Bug#934781: firmware-iwlwifi: iwl4965: Microcode SW error detected

2019-12-12 Thread Andrew Bettison
As an experiment, I downloaded the tarball from 
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tag/?h=20190815 
(as recommended in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939262 ), and manually 
copied its intel/* and iwlwifi-* files into /lib/firmware (overwriting 
the ones installed by the firmware-iwlwifi package).


After rebooting kernel 5.3.0-2 (amd64) I still get "iwlwifi: Microcode 
SW error" messages accompanied by "ieee80211 phy0: Hardware restart was 
requested" during periods of high Wi-Fi throughput, but they do not 
cause the Wi-Fi to hang.  So the newer firmware appears to rectify the 
worst part of the problem (Wi-Fi freeze) but does not fully resolve the 
problem.

Bug#946601: linux-image-4.19.0-6-amd64: High load by kworker, shutdown or reboot hangs

2019-12-12 Thread Olaf Skibbe

Hi all,

I would like to add a detail:

I checked today: on shutdown, the system hangs for at least 3 hours with 
the message


watchdog: watchdog0: watchdog did not stop!

This means: the machine did not reboot, I had to switch off the machine 
manually. I would therefore suggest to increase the severity.


I stored the complete dmesg output and can provide if wanted.

Cheers,
Olaf

Dear Maintainer,

I experience the following issue:

When the system is running for some time (usually a few days, but sometimes
some hours), the load rises to about 5. The kernel log (dmesg) shows this
message (and repeats it several times):


[196473.819189] INFO: task kworker/u16:0:19009 blocked for more than 120

The load then stays high until shutdown. It remains fully usable, top looks
like this:

top - 17:52:44 up 2 days,  6:57,  1 user,  load average: 5.43, 5.21, 4.32

MiB Swap:  32595.0 total,  32595.0 free,  0.0 used.  29682.1 avail Mem

At shutdown, the system hangs for about 20 minutes with the message "watchdog:
watchdog did not stop" (quoted from mind memory) until it finally shuts down.
This is always related to the increased load and the respective dmesg messages.

I experienced this behaviour about 20 times within the last few months. I did
not find any workaround t solve this situation.

Cheers,
Olaf
