Make sure that you have dma enable on your IDE disks . Basically, soft-updates does short bursts of disk activities which can crash a disk or slow down a system during the disk i/o operations using PIO. Yes, I have seen disks spin mindlessly due to the "intensive" short burts of disk io activities and the problem went away by switching to DMA. -- Amancio Hasty ahasty@mindspring.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
