Haven't seen that on FreeBSD since the 386 days. I have seen this on my box. Disabling one of the USB-ports solved the=20 problem. I was seeing very high IRQ-rates. Check $vmstat -i during the=20 process to see if you have abnormal high rate jumps. It might be that we=20 must investigate some of our drivers to play nice with each other. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart19258723.FsxZpdz3EZ Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBCk4NyXyyEoT62BG0RAifSAJ96oTPvpjnLyaZfqTlRz1faxSnlgwCdGuQK DZcxM17bL716dQgZ4bL9T6Y= =bYd9 -----END PGP SIGNATURE----- --nextPart19258723.FsxZpdz3EZ--
