From: "Dan Naumov" To: freebsd-gnats-submit@FreeBSD.ORG Cc: Subject: Re: i386/37420: Copying large files from an IDE CD-ROM to a harddrive causes a s Date: Thu, 25 Apr 2002 11:54:31 +0300 I decided to post a follow up to my bug-report seeing as I've managed to fix this problem. Apparently, PIO4 seems somehow broken with my chipset. Some folks on OPN #freebsd suggested me to look into the "atacontrol" utility and after switching the transfer mode on the 2nd controller from PIO4 (default) to UDMA33 solved all stability issues. I havent't done any *EXTENSIVE* testing, but so far, it definately looks much better. The problem used to cause a system lockup every single time I would attempt copying files off the CD-ROM, now I've transferred 3 600+ MB files without a problem. The following is now in my rc.local: #!/bin/sh /sbin/atacontrol mode 1 udma2 udma2 What I am wondering about, is what actually causes this particular problem with FreeBSD. I used this drive in Win2000, WinXP and Linux, which by default, use PIO without any problems. However, PIO mode apparently causes problems with FreeBSD. Is it something that I can expect to be fixed in the future FBSD releases or is using atacontrol to changing transfer modes the only possible workaround ?
