After install new kernel – 4.18.0-2-amd64, my computer’s startup is very slow and I can’t use my RT3090.
Of course, I had installed firmware-misc-nonfree and firmware-ralink (accoring this site, my wifi card should work well with it.

I try reinstall firmware-ralink and ignore IPv6 in network settings and it still not work.
I am in a chicken-egg situation for my secondary harddrive (non boot):
- My BTRFS mount has gone readonly because no space left.
btrfs filesystem resize only works on mounted volumes.
- I needed to umount this ro mount in force mode (because of device busy).
- If I try to mount rw it fails because of errors (most likely caused by no space left)
- If I try to run
btrfs check --repair it gives device busy
What to do to find out what keeps
/dev/sda busy? My hdd is listed in
/etc/fstab, does that matter (
UUID=262a8d86-279a-4f6b-8968-32e200c32255 /mnt/hdd btrfs defaults,compress=zlib 0 1)???
lsof | grep /dev/s -> nothing
lsof | grep /mnt/hdd-> nothing
- The same for
fuser -> nothing
mount -o recovery /dev/sda /mnt/hdd

If I try to run:
