I've a perfectly good PR about vinum (panics) open. There's no even single
follow up (kern/22103).
I couldn't stand it any longer, so I'm not able to recreate it since I'm
using raid1 on those disks now. I waited for almost one month but
aparently nothing was done. (I opened one PR before that but it was badly
formatted and had to become closed).
I understand that people have other things to do, and FreeBSD is volunteer
project, but we shall face the truth - the man page for vinum should state
that RAID5 is experimental and prone to crashes. It should be emphasized
that it shouldn't be used in sensitive environmets.
I know other people for whom it rendered their servers unusable.
I managed 8( to crash it today as well. I'll probably move to hardware
raid solution instead, I'm quite fed up with vinum.

I've a crash dump of today, perhaps I'll open another PR.
