If you've got a server running node Javascript you may want to skip Linux kernel 6.14.6.
I've installed it on about 25 machines and it's been stable on all but two, and two which have been unstable also happen to be the only two running node applications. I do not know exactly what is wrong with the kernel because the failure mode is one where it locks up hard, does not reboot, does not response to magic-sys-request, thus there is no way to get a kernel dump to see what it was doing when it dies.
