All,
I don't recall having this issue with 5.3-BETA2, but to be honest I
can't be entirely sure. I just put a fresh install of BETA3 on a P4
2.8GHz machine and while untaring ports.tgz I get bsdtar hovering
around 80% CPU usage. The machine becomes noticably sluggish, where
neither previous BETA did before. I find the "pcib1: could not get PCI
interrupt routing table for \\_SB_.PCI0.P0P2 - AE_NOT_FOUND" line in
my dmesg curious, but I'm not sure what, if anything, I can/should do
about that.
Should I recompile my kernel disabling WITNESS and the like? Below is
a complete dmesg; the motherboard is an Intel SE7210TP1-E. Please cc
me as I'm not subscribed to -questions.
Regards,
aaron.glenn
