Hi Drew,
Yes, the HWE kernel syncs automatically from the normal kernel as it
moves forward.
Once Disco gets the patch, the HWE from Disco in Bionic should get it as
well (same version number plus ~18.04.1 suffix).

Are there any plans to include this fix in the hwe kernel?
I tested today on the current 18.04 hwe kernel 5.0.0-27 and the bug appeared in
18min.

Drew,
Thanks for testing bionic-proposed!
So it will be resolved for bionic kernels shortly, when it hit bionic-updates.
Disco/19.04 will get this patch via stable updates in the near future
[1].
Eoan has it applied (LP: #1839588).
So this is all good.
Thanks again,
Mauricio

Stress tested bionic-proposed kernel 4.15.0-60-generic #67-Ubuntu for
6.5h with no errors so it appears to be patched in that version as
expected.

Hi Drew,
That's very good news! So it looks like that patch resolves the
problem.
Could you please test the kernel in bionic-proposed [1] (4.15.0-60-generic)
which has that patch to confirm it's also working correctly?
Thanks!

rc2 does contain the bug, annoyingly it took 54min to trigger which is longer
than any previous version.
rc3 is stress testing at the moment.

Hi Drew,
There's a mpt3sas fix in v5.3-rc3 for a problem that may cause an adapter

(although not sure of the exact fault state code; but it should cause a reset
anyway).
If you could please test either

Would it be possible for you to do a reverse kernel bisection?
First, find the first -rc kernel works and the last -rc kernel doesn’t
work from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then,
$ sudo apt build-dep linux
$ git clone
I let the stress test run on the mainline kernel for 22h, no errors.
