Hi,

I'm pretty sure the failure actually occurs with all three partitions,
but it is more severe with /usr because I cannot use the 'nofail' option
to ignore the failure.

Here's the relevant part of my /etc/fstab:
UUID=1ac3a9b3-2ced-4e6c-9378-f8c94ac2983e       /usr    ext4   
rw,errors=remount-ro,commit=600 0       1
# /dev/sda7
UUID=868996eb-2b9d-42eb-9bcc-2b23b89dc11b       /home   ext4   
rw,errors=remount-ro    0       0
# /dev/sdb4
UUID=0797ee37-d1b9-49ea-a865-c73682cd96a7       swap    swap   
sw,nofail       0       0

Here's the output of `lsblk -o NAME,UUID,LABEL`:
NAME   UUID                                 LABEL
sda

├─sda2

└─sda8 84f3e7a4-c3af-4ac1-a789-cc554395a50b 
sdb

└─sdb4 0797ee37-d1b9-49ea-a865-c73682cd96a7 Swap

And here's the relevant parts of the output of 'mount' after booting the
system (pressing ctrl-d after the timeout) - notice that /usr and /home
are mounted correctly:
/dev/sdb2 on /usr type ext4
(rw,relatime,errors=remount-ro,commit=600,data=ordered)
/dev/sda7 on /home type ext4
(rw,relatime,errors=remount-ro,data=ordered)

And the output of `swapon -v:
NAME      TYPE      SIZE USED PRIO
/dev/sdb4 partition 9.3G   0B   -1
