All I know myself in the past have tried to cache an embedded encrypted
LVM in a regular home system.
The problem was probably caused by the SSD not clearing write caches
fast enough but I too got some 2 minute "hanging process" outputs on the
So it was probably a queueing issue within the kernel and might not have
been related to the cache,
but I'm still not sure if there wasn't an interplay at work.
The main cause was a way too slow SSD but at the same time... that sorta
thing still shouldn't happen, locking up the entire system.
I haven't had a chance to try again with a faster SSD.
