Re: kern/54818: 9.0_RC1 pagedaemon spins
Oh, BTW, I also appear to have this problem on my old Lenovo T60
laptop, which runs 8.1/i386 and has 3070MB usable physical memory, and
it's apparently easier to get this one to trigger.
I'm assuming it's the same issue. I've not dragged over the diffs to
this host (yet).
Anything more relevant to collect?
