For Ubuntu Bionic release, the latest supported version is
4.18.0-1ubuntu2~ubuntu18.04.1.
The iproute2 5.x versions are supported in other releases (Eoan, Focal).

Public bug reported:
We can reproduce a crash in the block layer with lots of stress on lots
of SCSI disks (on an XIV storage server).
We seem to have several scsi stalls in the logs/errors (needs to be
analyzed further) but in the end we do crash with this this calltrace.

No, and I do not see why this was mirrored at all. This is no bug, this
is absolutely normal behaviour since like forever.

I've only seen this happen with manually using the installkernel script with
the commands included in my first comment. I will have to try if it also occurs
with "make install" in a kernel tree. I currently have a small

So 5.4.0-34.38 (only 34.37 kernel images and meta package linux-generic=33.38
were available before) was just tagged few minutes ago from master-next to
include this patch.

Hi,
As of today the kernel 5.4.0.33.37-38 in focal-proposed doesn't seem to
have this patch pulled in.
It seems it was only pulled in master-next branch this morning :
