Hi Yannis,

Hi Johannes,

Do you have a machine with a bcache setup running where you can reproduce the
error? Or do you know a method to reproduce the error?

I don't know how to reproduce this issue. As I told the server was running 
correctly in production for more than 6 weeks when the problem appeared.
This server is still running Bcache in production for now...

No idea what trigger this :/

What I'd be interested in is which locks are held when it locks up (you can
acquire this information with SysRq+d or echo d > /proc/sysrq-trigger.

I'll try to get those informations if the bug strikes again.

Regards,
