Then a number of upgrades were installed, including a new kernel. Thereafter it crashed with kernel panic: out of memory. Found some advice that grub needed some adjustments to it's setup and update, but it did not help. The machine boots ok on the previous kernel, it may look like the bug is in kernel vmlinuz-5.15.0-67-generic. /var/log/kern.log looks like it has only reports from the ok kernel, out of memory is not mentioned. /proc/version contains the name of the ok kernel. lspci-vnvn.log is attached. ubuntu-bug linux says everything ok.
