Hi Kai-Heng, thanks for your response.
I followed your advice and installed these packages from the ppa:
linux-headers-5.3.0-050300rc5_5.3.0-050300rc5.201908182231_all.deb
linux-headers-5.3.0-050300rc5-generic_5.3.0-050300rc5.201908182231_amd64.deb
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.
ubuntu 18.04 (kernel 4.15.0) (mpt3sas driver 17.100.00.00) BUG
ubuntu 18.04 hwe (kernel 5.0.0) (mpt3sas driver 27.101.00.00) BUG
ubuntu 18.04 mainline
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.

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.

I let the stress test run on the mainline kernel for 22h, no errors.
so in summary:

rc3 has been stress testing for 7h without error so I believe Mauricio
Faria de Oliveira correctly identified the patch that corrects this
issue.

Public bug reported:
[summary]
when a server running ubuntu 18.04 with an lsi sas controller experiences high
disk io there is a chance the storage controller will reset
this can take weeks or months, but once the controller resets it will keep
resetting every few seconds or few minutes,
