Interesting, I re-enabled ccache on an ext4 partition (HDD) and worked
fine. So I suspect it's something to do with btrfs and SSD. My mount
options are:
/dev/sda3 on /home type btrfs (rw,relatime,ssd,discard,nospace_cache)
The problem is that I can't get hold of kernel panic since it's not in
the journal [1]. I don't know a way to get hold of the kernel panic log
to help anyway.
What would it be useful to debug it?
Setup netconsole, you can set it to go to a different box and then on
that box run
nc -lu -p 514 > out.txt
and then reproduce the panic. If you are using fedora you can install
netconsole and edit /etc/sysconfig/netconsole and set SYSLOGADDR=<your
other boxes address>. Thanks,
Josef
