A disk decided to just disappear from the array (this is a 12-disk
RAID6-data/RAID1C4-metadata array) a few hours ago, and I've started a
replace with a hot spare. The array had an unusually bad event a few
months back with a disk starting to show some read failures, and dying
in the middle of a scrub. Replacing it revealed a lot of errors all
over the array, though I couldn't identify the reason. Memory
corruption was a suspect, but the memory didn't show any errors upon
extended testing. I had a few uncorrectable errors still lingering
around while this other disk died, in case this could be part of the
problem here.
A few moments after the replace started, the machine went
unresponsive. After rebooting and remounting degraded to continue the
replace, while observing the dmesg output, I started seeing the kernel
errors and the machine can't access disks anymore. I was on an Ubuntu
HWE kernel (currently on 5.8) at the time, but I tested the latest
5.12 and it also throws similar GPFs. Even the main disk won't sync
anymore after the errors, so getting the logs out is a bit
complicated, but if it helps with logs from another kernel I'll get
some.
I did replace the machine memory to be sure that wasn't the problem,
so if something is bad, it would e the processor, which is very
unlikely. Also no other piece of software there has had any trouble so
far.
Here's what I could capture:

It'd be useful to see the storage stack:
lsblk -o NAME,FSTYPE,SIZE,FSUSE%,MOUNTPOINT,UUID,MIN-IO,SCHED,DISC-GRAN,MODEL
It's fine to omit the UUID. Mainly I just want to see all the physical
devices, their partitions, and how everything is being assembled to
make up this Btrfs file system.
Also useful info
sudo btrfs filesystem usage -T /mntpoint

Setup is a bit unusual, BTRFS is running over BCACHE, whole
unpartitioned disks, here's the raw data, removed the unrelated disks:

Currently mounted degraded,readonly. Didn't explore much yet, but
overall seems "fine" (as much as fine as a RAID6 missing a disk can
be).
