After upgrading from 18.04 to 21.04, my XPS 13 fails to boot, giving
the message "a TPM error (2314) occurred attempting the self test".
How can this be fixed? Thanks, jason

Title:
TPM intermittently
Tested the latest OEM kernel from -proposed on a Dell Edge Gateway 3000
running Ubuntu Server 18.04 LTS:
# rmadison linux-image-oem | grep bionic-proposed
linux-image-oem | 4.15.0.1035.40 | bionic-proposed | amd64
# dpkg -l | grep linux-image-oem
ii linux-image-oem
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag

Yes, that's correct according to the SRU cycle announcement here:
Before installing proposed kernel:
admin@1234567:~$ uname -a
Linux 1234567 4.15.0-1031-oem #36-Ubuntu SMP Mon Jan 7 09:40:58 UTC 2019 x86_64
x86_64 x86_64 GNU/Linux
admin@1234567:~$ dmesg | grep -i tpm
[0.00] ACPI: TPM2 0x76D60D78 34 (v03Tpm2Tabl
0001 AMI
(the commands run in the previous comment have been run on a Dell Edge
Gateway 3000)

@Tyler
So it looks like we landed this just in time for the new SRU cycle,
which means we're looking at a tentative release to proposed on Mar 25.
Does that sound right? If so, I may check with Anthony to see if there's
a possibility that linux-oem could possibly re-spin and release
earlier...

Khaled has applied my backport to the Bionic tree. linux-oem will soon
inherit it (within the same SRU cycle).

Just curious as to why this is now FixCommitted? Has Tyler's back-port
landed in git for the next OEM and/or mainline kernel SRU release?
