Public bug reported:
A hardware partner has been testing 18.04 subiquity images on their
servers with VROC enabled and configured in a RAID 10 setup.
In their own words:
Steps to reproduce:
1. Boot into VRoC controller in uEFI Setup and create a raid10 disk.
2. Install Ubuntu 18.04.5 on the RAID10.
3. The system hangs at "Partitions formatting 33%".
After looking at the launchpad
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578/), the fix
was included in the updated kernel.
[Quotes from the launchpad]
The released kernels are:
Hirsute: 5.11.0-22-generic
Groovy: 5.8.0-59-generic
Focal: 5.4.0-77-generic
Bionic: 4.15.0-147-generic
I've asked them to also confirm this on 20.04.2, and check that 20.04.3
dailies fix the issue.
It is at least a very reasonable hypothesis that this will also break on
all current ISO installs as none of them are respun once released to
include updated SRUs in the installation media. This currently affects
20.04.2 but that will be resolved shortly when 20.04.3 releases as the
GA and HWE kernels in that image should have the SRU that fixes this
issue. However, 18.04 has no further releases, and even the 18.04.5
daily-live and daily images on cdimages.ubuntu.com are not built after
18.04.5 was released.
