Bug#893393: linux-image-amd64: Kernel panic on active outgoing traffic through Huawei E173 modem in NDIS (CDC) mode
Package: linux-image-amd64
Version: 4.14+89
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
This bothers me from November 2017, when wvdial broke and I moved to
NetworkManager. While wvdial uses only serial interface (ttyUSB),
NetworkManager sometimes recognizes the modem as ttyUSB and sometimes as
cdc-
wdm. So maybe the bug is much older as I was not actively using
huawei_cdc_nbm
module before.
Since that, I started to experience strange system crashes. The only common
thing for them is that HDD activity stops and the cooler keeps working; the
system doesn't respond to anything including REISUB. The screen image was
simply freezing for first weeks, then it started cluttering when crash
happens.
I was not sure if this is a software problem or a hardware one. I
couldn't even
strictly determine what conditions lead to this. The only mostly common
thing
was that it happens on active outgoing traffic (file uploading, torrents
seeding and so). But not sure if every time. Sometimes the issue huddled
and I
could calmly upload large files for several days or even several weeks, but
then crashes started happening again.
People on a forum suggested me to install crash/kdump. Sometimes kdump
triggers
on kernel panic, sometimes it doesn't and I still get an unresponsive system
with a cluttered screen. When it triggers, systemd tries to start the
bunch of
services in a small amount of RAM, so it proceeds very slowly and
finally hangs
or fails to the maintenance mode because of expired timeouts. Today I
found out
that in maintenance mode I still can run the kdump service and successfully
collect the kernel dump and dmesg.
