This is just printing out the CPU features bitmasks. The difference is that the CPU identification code in 6.x looks at the bitmap returned in %ecx after a cpuid 1. The features were always there, 6.x just prints them out. As for usefulness...

No. 6.x is just more verbose. I thought these had all been hidden behind 'verbose' as they are primarily hints to the developers. >-pci0: <serial bus, USB> at device 29.7 (no driver attached) >+ehci0: <Intel 82801DB/DBL/DBM (ICH4) USB 2.0 controller> mem >0xf4fffc00-0xf4ffffff irq 11 at device 29.7 on pci0 >+ehci0: [GIANT-LOCKED] > >Kudos!

Which bit? The TSC is notoriously unstable and a relative change of 1.2e-7 can be ignored. If you look at kern.clockrate, you'll see that hz now defaults to 1000. >-acd0: CDRW <HL-DT-STCD-RW/DVD-ROM GCC-4241N/A100> at ata1-master PIO4 >+acd0: CDRW <HL-DT-STCD-RW/DVD-ROM GCC-4241N/A100> at ata1-master UDMA33 > >That's *very* nice! Again, that's just a change in defaults. Problems were found with DMA to ATAPI devices so the decision was made to default to PIO4 in 5.x. You can set hw.ata.atapi_dma to 1 in 5.x if you want to (see acd(4)). -- Peter Jeremy _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
