My home server only stays up for a day or two before some process (changes every time) causes a soft lockup and the machine freezes, requiring a hard reset. journalctl -b -k logs of the last two lockups can be found here and here. The traces that the kernel prints when the BUG happens always show functions having to do with pages.
So far, I have tried:
Updating the kernel. This is usually the first thing suggested, understandably, but these freezes have been happening since 5.10
Ensuring amd-ucode is installed and updating the microcode:
drew@leo% sudo dmesg | grep microcode
[ 0.368507] microcode: CPU0: patch_level=0x08108109
[ 0.368511] microcode: CPU1: patch_level=0x08108109
[ 0.368515] microcode: CPU2: patch_level=0x08108109
[ 0.368528] microcode: CPU3: patch_level=0x08108109
[ 0.368532] microcode: Microcode Update Driver: v2.2.

Running stress, smartctl tests, and memtest86 to check CPU, disks, and RAM, respectively
The list of computer parts is here. What else can I try to figure out what is going on?
