Hi @hui.wang,
the RPi4 boots off the sdcard normally but then I use a USB3 enclosure
with disks to assemble a RAID1 BTRFS device to be used as rootfs. At the
end of the boot, there is no /dev/mmcblk0* device:
#> ls -ld /dev/m*
drwxr-xr-x 2 root root 80 Nov 30 15:42 /dev/mapper
crw------- 1 root root 10, 227 Nov 30 15:42 /dev/mcelog
crw-r----- 1 root kmem 1, 1 Nov 30 15:42 /dev/mem
crw------- 1 root root 10, 56 Nov 30 15:42 /dev/memory_bandwidth
drwxrwxrwt 2 root root 40 Nov 30 15:41 /dev/mqueue
Anyway, this is just "an annoyance" that makes just a bit harder to
switch kernel, the real problem is this one:

According to this thread
(https://bugzilla.kernel.org/show_bug.cgi?id=202541) every kernel >=
4.20 is affected and there's still no patch in 5.3. I'll try to go back
to some 4.19.y kernel, I'm even prepared to lower the memory to 1 Gb,
cause so far this raspberry hasn't had more than a day of consecutive
uptime.
