--- Comment #24 from Tomi Sarvela <tomi.p.sarvela at intel.com> ---
If you see /sys/fs/pstore, then the feature is enabled and working.

Next thing is to configure linux to write dmesg buffer to pstore when panicing,
and the important thing is to panic. Add to command line:

nmi_watchdog=panic,auto panic=5 softdog.soft_panic=5

(5 on the command line means 5 seconds)

Unfortunately, in many suspend/hang issues nothing gets written to pstore
because CPU is not available. Pstore is a last resort thing, a bit like
console: it might help, or it might stay silent.
