According to: https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.4.7-Stable-Released
"Greg Kroah-Hartman took time out of his New Year's Eve festivities to release Linux 5.4.7, 4.19.92, and 4.14.161 as the newest supported stable releases of the Linux kernel.
Making these kernels noteworthy is that they contain the necessary MCE fix for booting the new AMD Ryzen Threadripper 3900 series processors. With Linux 5.5 mainline or these back-ported kernels, Linux should be booting now without issue.
These stable kernel updates also add Intel Comet Lake PCH-V and Elkhart Lake SoC support to the intel_th driver. But the rest of the changes are an assortment of mostly mundane fixes, unless you happened to be affected by one of the particular bugs addressed."

The kernel SRU workflow project is a special project that is only used for internal processes. Your bug should have been filed against the ubuntu/linux project which I have now fixed. Also note that we closely follow upstream stable releases and automatically pick them up.
