Bug#942563: linux-image-5.2.0-3-amd64: iwlwifi continously restarts
Package: linux-image-5.2.0-3-amd64
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Trying to use wifi under new kernel
* What exactly did you do (or not do) that was effective (or
ineffective)?
Install new kernel and try to turn on wifi card
* What was the outcome of this action?
wifi card continously restarted and wifi almost does not work
* What outcome did you expect instead?
Working wifi
When I install new kernel my wifi starts continously restart, when i do:
(xz -dc /var/log/syslog-2019*.xz; cat /var/log/syslog-20191018 /var/log/syslog) |grep 'Microcode SW error detected' |less -N
i got
