From: Linh Pham <question@closedsrc.org> To: bug-followup@freebsd.org, aces@thrillkill.de Cc: Subject: Re: sparc64/82261: DMA-support on Sparc64 broken Date: Wed, 27 Jul 2005 19:25:22 -0700 I just wanted to report that I experienced the same problem with my Sun Blade 100 system (using both the stock Sun hard drive and two off-the-shelf drives, one Seagate 7200.7 ATA100 and an older WD 8GB) running 5.4-RELEASE. I'm guessing this impacts all Blade 100/150, Netra X1 and Fire V100 servers as they all seem to use the same chipset (give or take a little bit). Setting hw.ata.ata_dma to 0 does fix the problem with my Blade 100 (and Blade 150, nearly if not identical motherboard but US-IIi instead of US-IIe). I haven't run into the same problem while running 5.4-RELEASE or 6.0-BETA on a Sun Ultra 10 using a Seagate Barracuda IV 40GB drive; probably because it uses a different ATA controller (which isn't great to begin with). -- Linh Pham question@closedsrc.org http://closedsrc.org/
