Subject: 5.4.8: WARNING: CPU: 7 PID: 5905 at mm/slab.h:473 kfree+0x9c/0xb0


Hello,

Under some 'heavy' I/O the screen froze, but the mouse  pointer could
still be moved.
Harddisk LED went out and only an occasional flash could be observed.
Ctrl-Fx did not work.
ssh did not work.

So I shut the PC down, rebooted with Ctrl-Alt-SysRq-whatver.

The I/O consisted of the RAID-10 resyncing, some filed being moved to
SD-card via USB3, some downloads going on at slowish speed.

This is AMD Ryzen 5 3400G with Radeon Vega Graphics on Gigabyte X570
AORUS PRO running fedora 31 with kernel.org, git mesa, etc.

Log below.

Kind regards,
Udo
