Same symptoms here - on a [past history] stable system. Experienced a system lockup with linux-image-5.4.0-40-generic yesterday, while working at an x terminal ssh'ing into a remote host. Have rolled back to linux-image-5.4.0-39-generic now.
Completely different hardware to your spec - AMD A10 here, unfortunately no ILO to retrieve any useful crash information. No messages/syslog "interesting" events reported in post-analysis. At the time there was no network response, mouse, kbd, sysreq, disk activity, complete freeze. Hard reboot required. Stable now back on linux-image-5.4.0-39-generic. Also moved from bfq io scheduler back to mq-deadline as I found lockup issue reports here too. ymmv.
