Message-ID: <20010403023412.A54627@dva.in-berlin.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello, I can't get my system working stable _until_ I define ATA_ENABLE_WC in my kernel-config! I get this message _many_ times when I write to my Fujitsu 40GB-Harddisk: /kernel: ata3: resetting devices .. done /kernel: ad6: WRITE command timeout tag=0 serv=0 - resetting There are not only those annoying messages but also there are very long access delays (5-10 secs!). During these delays the disk-access LED stays red and there is absolutely no response from the _entire_ disk I/O-system. Turning off WC by default may break the stability of some harddrives! Anyone out there who can verify that with a FUJITSU "MPG3409AT E"? IMO this behavior should be clarified before 4.3-Release!
