...or device ad1: 76319MB <ST380013AS> [155061/16/63] at ata0-slave UDMA33 I read somewhere that this message is a hoax and that the drive should actually work in UDMA150. Is this my case? I also checked the source of ata-dma.c: Here is the section. #if 1 if (udmamode > 2 && !atadev->param->hwres_cblid) { ata_prtdev(atadev,"DMA limited to UDMA33, non-ATA66 cable or device\n"); udmamode = 2; } #endif Maybe this should sound like: if ( (udmamode > 2) && (udmamode < 5) && (!atadev->param->hwres_cblid) ) { ata_pr...

Here's a patch against 4.8-RELEASE kernel that allows disk writes on softupdates-enabled filesystems to be delayed for (theoretically) arbitrarily long periods of time. The motivation for such updating policy is surprisingly not purely suicidal - it can allow disks on laptops to spin down immediately after I/O operations and stay idle for longer periods of time, thus saving considerable amount

I am having problems with silent data corruption on (some) drives connected to an MCP55 SATA controller. I have two servers, both running RELENG_7_0/amd64. One has the 570 Ultra chipset, the other has 570 SLI. Both chipsets have the MCP55 SATA controller. The server with 570 Ultra chipset has a bunch of older 250GB SATA-150 drives hooked up to the MCP55 controller and it is working just fine.

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed
