A buildworld just > took 22.5 hours! I use 5046A-XB with i7-930 as home workstation, running latest RELENG_8, and I do not have the problem you noted. My BIOS is v1.1, USB legacy is enabled. I did noted one issue with hw, built-in firewire controller generated too high interrupt rate, so I usually do not load firewire.ko unless needed. >=20 > bryce@tahiti[~]>uname -a > FreeBSD tahiti.bryce.net 8.1-STABLE FreeBSD 8.1-STABLE #0: Tue Sep 7 > 22:45:38 CDT 2010 > root@tahiti.bryce.net:/usr/obj/usr/src/sys/GENERIC amd64 >=20 > I have disabled "Legacy USB Support" in the BIOS and that helped, but > I'm not finding any other setting that are getting things where they > need to be. >=20 > I have tested the two system drives independently (currently a zfs > mirror), so it is not likely to be an hdd issue. >=20 > Here's the verbose dmesg boot details - http://www.bryce.net/files/dmesg.= boot >=20 > And, the IPMI ASL in case that is of any value - > http://www.bryce.net/files/tahiti.asl >=20 > Currently, I'm not running powerd, performance is not better with it runn= ing. >=20 > root@tahiti[/usr/src]#cat /boot/loader.conf > ahci_load=3D"YES" > coretemp_load=3D"YES" >=20 > zfs_load=3D"YES" > vfs.root.mountfrom=3D"zfs:system" > #vfs.zfs.prefetch_disable=3D1 >=20 > kern.maxfiles=3D16384 >=20 > # async i/o > aio_load=3D"YES" >=20 > # VirtualBox > #vboxdrv_load=3D"YES" >=20 > # SMB > #ichsmb_load=3D"YES" > #smb_load=3D"YES" >=20 > # Power Saving > #kern.hz=3D"100" >=20 > # Disable APIC subsystem - no longer needed when disabling lapic below > #hint.apic.0.disabled=3D"1" >=20 > # Disable local APIC (LAPIC) timer - for C3 state > #hint.apic.0.clock=3D"0" >=20 > # Avoid 128 interrupts/sec per core, at cost of scheduling precision > #hint.atrtc.0.clock=3D"0" >=20 > # Disable throttle control (and rely on EIST) > hint.p4tcc.0.disabled=3D"1" > hint.acpi_throttle.0.disabled=3D"1" >=20 > Thanks in advance for your time! >=20 > ::Bryce:: > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" --mW9eGbZzDIYYWqGs Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkyUyxwACgkQC3+MBN1Mb4gi0wCcD3fpHHFQ8JecMfABQbN6rXcV LvkAn0gOswTY82qWrK2wot8KG2BimY6/ =Rh4O -----END PGP SIGNATURE----- --mW9eGbZzDIYYWqGs--
