Some times I get the following errors at dmesg and syslog: Sep 18 14:03:38 pc kernel: g_vfs_done():ufs/home[WRITE(offset=50879266816, length=131072)]error = 1 Sep 18 14:04:05 pc last message repeated 287 times Sep 18 14:07:43 pc kernel: g_vfs_done():ufs/home[WRITE(offset=50879283200, length=131072)]error = 1 Sep 18 14:08:06 pc last message repeated 216 tim They repeat endless until reboot. There the kernel gives up the buffers which leads to a dirty file system and maybe also data loss. However I don't belive the harddisk is broken because it is new and SMART reports no errors at all. I use the SATA adX device with gbde encryption. Here are some information about: (full dmesg is attached) atapci1: <nVidia nForce MCP67 SATA300 controller> port 0xf80-0xf87,0xf00-0xf03,0 xe80-0xe87,0xe00-0xe03,0xdc00-0xdc0f mem 0xfbe76000-0xfbe77fff irq 23 at device 9.0 on pci0 atapci1: [ITHREAD] atapci1: AHCI Version 01.10 controller with 4 ports detected [...] ata4: <ATA channel 2> on atapci1 ata4: [ITHREAD] [...] ad4: 476940MB <SAMSUNG HD502HI 1AG01118> at ata2-master SATA300 su:/home/martin$ geom bde list Geom name: label/home.bde Providers: 1.
