Brief summary

"Hardware Error" reported by Linux (all versions from 5.0 to 6.10)

How reproducible

Every couple of hours or so

How to reproduce

Boot a linux kernel

Expected behavior

No hardware errors reported

Actual behavior

Frequent error reports - albeit all "corrected"

Screenshots

[301707.243573][T16741] [Hardware Error]: Corrected error, no action required.
[301707.250737][T16741] [Hardware Error]: CPU:0 (16:30:1) MC0_STATUS[Over|CE|-|AddrV|-|-|-]: 0xd400000000010015
[301707.260632][T16741] [Hardware Error]: Error Addr: 0x00007fc39a4d8000
[301707.267218][T16741] [Hardware Error]: MC0 Error: L1 TLB multimatch.
[301707.273701][T16741] [Hardware Error]: cache level: L1, tx: DATA

The Error Addr changes, the remainder of the information is static.

Additional context

This may not be a firmware issue or firmware-correctable, but I thought I'd ask in case anything can be done in the new Dasharo firmware releases?

… seems to describe a very similar problem, but was resolved many years ago, and booting with nopti had no effect.

Further, on every reboot there's a ~20 second delay whilst starting the kernel:
