Henryk Paluch <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #6 from Henryk Paluch <[email protected]> --- I can confirm this problem still exists in FreeBSD 13.2-RELEASE. I found that trivial patch (that just copies DMA quirks from ata-siliconimage.c fixes problem for me. What I observed so far: - the corruption occurs on every SATA disk (tested SATA-1 Maxtor, SATA-2 Seagate, and SATA-2 WD) when connected to MCP55 SATA controller. In my case on-board controllers on: - K9N Platinum (MSI MS-7250) - 8GB RAM - AMD X2 (dual-core CPU) I have found that corruption does not occur if any conditions below are met: 1. Boot in "Safe mode" (where DMA is disabled, and PIO forced) 2. Use any other SATA controller - in my case even old SiI3112A (BIOS dated 2002). 3. Use above patch that just copies DMA quirks from ata-siliconimage.c Not sure if there are still any users of such nVidia chipset (it was popular around 2008). -- You are receiving this mail because: You are the assignee for the bug.
