Very much so. What is a "hangcheck timeout"?

My wife has kindly bought the basics I need for a new PC for my birthday
(yeah! :-) and I've ordered two Seagate Ironwolfs to go with it, so I
will be setting this up from scratch. Raid, KVM, LVM, the works. So
hangcheck timeouts, documenting on the wiki, all the other bits, the
important thing is I'll have a brand new system I can play with that's
not got anything important on it and if the system (software side only,
of course :-) gets trashed, so what. I can try stuff out without
worrying about putting my live system at risk.

But back to topic. I know we have the disk timeout (on desktop drives,
any random number up to 180secs :-). We have the linux i/o wait timeout
- by default 30 secs. And now we have the hangcheck timeout, whatever
that is ...

Cheers,
Wol
