Package: src:linux
Version: 4.9.82-1+deb9u3
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
If both the MTU and channels are set using ethtool the Microsoft Hyper-V
network drivers crashes.
The network driver gets stuck in a loop and causes one or more kernel threads
to consume all
processing power. In turn, this sometimes triggers a CPU soft lockup. Microsoft
already fixed
the issue and pushed the patch upstream. The patch has been tested and solves
the issue for this
Debian and kernel version. The kernel module should be updated to include the
patch.
Thanks,
Y.
