I just got a MSI P6N SLI board with the MCP51 chipset. It uses the sata_nv driver for the SATA drives. I've been running into a couple of issues and I was wondering where I might start to debug this. I'm running 4 SATA drives on raid10. For some reason, the last 2 SATA ports just "die" and then I'm left with 2 drives in the raid10 config. To get the ports back to working state, I have to reboot. I've run badblocks on the drives and even replaced them with new drives as well. I've run into this issue twice and it's not like it happens all the time. Most of my components are pretty new as I just built this system about 3 weeks ago. Since both drives passed the badblocks test, I've just re-added them to the raid10 pool and let mdraid get them in sync. So far, no issues for the past 3 days but I'm curious to see what the issue might be. Here is the snippet of dmesg when the drives died: -- Jul 22 17:59:33 miyagip -- MARK -- Jul 22 18:19:33 miyagip -- MARK -- Jul 22 18:35:56 miyagip kernel: [ 3424.673318] nf_queue: full at 1024 entries, dropping packets(s).
