In this instance, I wonder if we should do the extra checks. The kernel

machines runs an older kernel for now. (Dave's latest patches seem to
help a lot there, but you get the point.)
Can you be more specific? Do you still experience instability due to cache / TLB issues
on this machine?
Sorry for the delay. Our main machine, 'muta', has been suffering
instability for a while. It ended up also having bad RAM and failing
disks. We've now replaced them last night.
We had a lot of kernel crashes since then but after upgrading to
6.10.11, everything seems okay so far.
FYI, Dave's commit 72d95924ee35 ("parisc: Try to fix random segmentation faults in package builds") [1]
was a game-changer for the parisc kernel. It went into kernel 6.10 and since then
our 64-bit debian builds run absolutely stable.
