I just tested 5.4.0-rc3-00037-g3b1f00aceb7a on 3 parisc machines and did a gentoo world emerge
after boot for test. On my rp3440, I got a build failure of one package and the
following in dmesg. While userspace apps can crash with invalid behaviour any time, this
one looks like kernel trouble to me - Data TLB miss fault. It was not easily reproducible, next
world emerge ran fine past that package.

The ambient temperature in the room was 32 degrees Celsius, so hot but not too hot hopefully.
Nothing in BMC logs so hopefully not hardware trouble but slightly unsure.
