Well, v5 passes 0day, so all previous reports are fixed.
But there is a new one about reboot on parisc platform which takes ~3
mins after the patch with ldisc locked on tty_reopen().

I believe it's related to holding read side for too long..
So, the patches still need another fix, heh.

Unfortunately, I was a bit busy with other bugs hitting more in Arista.
