I have to disable the APIC for the system to stay up more than 2-5 minutes. When doing that, the computer seems stable, it can run for 12 hours, with no weird messages in the console, except, of course the following problem. If no-one else are experiencing this, it's obvious that this bug should be ignored. When I try to mount the Serial ATA disk, the following messages appear in the console: ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=12063 ad4: TIMEOUT - WRITE_DMA retrying (0 retries left) LBA=12063 ad4: FAILURE - WRITE_DMA timed out LBA=12063 g_vfs_done():ad4s1d[WRITE(offset=6144000, length=8192)]error = 5 ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=12063 ad4: TIMEOUT - WRITE_DMA retrying (0 retries left) LBA=12063 ad4: FAILURE - WRITE_DMA timed out LBA=12063 g_vfs_done():ad4s1d[WRITE(offset=6144000, length=8192)]error = 5 The S-ATA controller is located on the motherboard. It is an Asus A7N8X. Output of pciconf -lv for the S-ATA controller: hdr=0x00 vendor = 'Silicon Image Inc (Was: CMD Technology Inc)' device = 'SiI 3112 SATALink/SATARaid Controller' class = mass storage subclass = RAID It is possible to view the files on the filesystem, and to write to it when it is mounted this way, but I suspect that data is lost, or will be lost, if it is used extensively. When setting the drive to PIO4-mode using atacontrol, the errors do not appear, and everything works as expected. When mounting in read-only mode, it can read flawlessly (with DMA enabled). The hard drive is a Seagate, with 80GB: ATA channel 2: Master: ad4 <ST380023AS/3.01> ATA/ATAPI revision 6 Slave: no device present I have CVSup'ed to the most recent version of RELEASE-6.0. The problem did not occur on Windows, so it's not an (obvious) case of broken hardware. ACPI disable/enable changes nothing. >How-To-Repeat: With the described hardware, the problem appears once one tries to use the drive. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
