FreeBSD unstable on Dell 1750 using SMP?

[Rutger Bevaart]

Hi Kris,

I cannot find anything about that in the /usr/src/UPDATING for the 5.4
branch. We're running "FreeBSD xyz 5.4-RELEASE-p5 FreeBSD 5.4-RELEASE-p5"
and p6 and later only fix some IPSEC and SSL stuff.

Is it in 6.0 and if so, will somebody backport that fix?

Regards
Rutger
