Bug#870523: linux-image-4.11.0-1-amd64 confirmed broken on another computer
Hi. I've just upgraded another computer from "jessie" to "stretch"; this installed 4.11.0-1 by default, and on that machine the problem immediately showed up: * load average going up within seconds after the boot * trying to install "nvidia-legacy-check" led to "apt" hanging (and and next reboot, it reported the package as broken, wanting to reinstall it before removing it leading to hanging again...) $ uname -a Linux night 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux That one seems to work, for now... Regards, Gilles

Bug#869658: linux: system freezes when dell-smm-hwmon reads fan speed
In my system, dell-smm-hwmon is linked to the following folder: /sys/class/hwmon/hwmon2/ The freeze occurs only when I type the following commands: cat /sys/class/hwmon/hwmon2/fan1_input cat /sys/class/hwmon/hwmon2/fan2_input cat /sys/class/hwmon/hwmon2/fan3_input In these commands, the freeze does not occur: cat /sys/class/hwmon/hwmon2/temp1_input cat /sys/class/hwmon/hwmon2/temp2_input cat /sys/class/hwmon/hwmon2/temp3_input cat /sys/class/hwmon/hwmon2/temp4_input In this link, more information: https://bugzilla.kernel.org/show_bug.cgi?id=112021
Bug#870523: linux-image-4.11.0-1-amd64: Same problem on "4.11.0-1-amd64"
Package: src:linux Followup-For: Bug #870523 Dear Maintainer, * What led up to the situation? Running for about 10 days without the problem appearing. Then, executing commands such as * mvn * ps * df * kill * sync * reboot * What exactly did you do (or not do) that was effective (or ineffective)? The terminal freezes. Load average is reported with insanely high values: $ uptime 13:28:26 up 10 days, 11:02, 17 users, load average: 48.13, 48.05, 47.62 Only a hard-reboot is effective to come back to a usable state. Unfortunately, very few hints exist on the Web that could point at the cause of the problem (searching for "blocked more than 120 seconds").

And even managed to come up with a patch that got accepted in the
wireless-drivers-next tree[1]. It does not apply to 4.12, therefore I
have attached a version which does. Alternatively you could cherry-pick
commit f2764f61fa10 ("rtlwifi: Fix memory leak when firmware request
fails")[2] before it.
Cheers,
Sven

Subject: [PATCH] rtlwifi: Fix fallback firmware loading
Commit f70e4df2b384 ("rtlwifi: Add code to read new versions of
firmware") added code to load an old firmware file if the new one is
not available. Unfortunately that code is never reached because
request_firmware_nowait() does not wait for the firmware to show up
and returns 0 even if the file is not there.
Use the existing fallback mechanism introduced by commit 62009b7f1279
("rtlwifi: rtl8192cu: Add new firmware") instead.
Fixes: f70e4df2b384 ("rtlwifi: Add code to read new versions of firmware")
