But when I use sysctl to switch the ATA driver from dma mode to pio mode, the same cp command works correctly. Is this the problem of ata driver? >How-To-Repeat: Everytime when you copy a lager file about 600MB from the HD which ataches on ATA100 to itself under UDMA5 mode. >Fix: Sorry, I am not able to fix it. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
