Hi, I cannot boot above kernel when I *disable* swncq support which got added in sata_nv. Problem seems that some component thinks driver is in ncq mode while it is not, as I see a queue depth of 31 instead of 0 on boot., ie I see something like this: ata1.00: 625142448 sectors, multi 1: LBA48 NCQ (depth 31/32) though I disabled ncq.And then boot "hangs" at sd 0:0:0:0: [sda] 625142448 512-byte hardware sectors (320073 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda while detecting partitions I guess. (Note, the boot messages are from ncq enabled kernel, but look alike, at least regarding queue depth...) The kernel doesn't really hang but tries detecting something while spitting out some errors. I simply wasn't patient enough. Anyway, I tried 2.6.23 with swncq patch on top, and here I don't have any problems with swncq or w/o it. (NCQ depth also gets correctly reported). I diffed the 2.6.23 patched driver with git one and they are nearly identical excpet some ID changes, whcih don't affect me, es I have a MCP51 chipset. So something in libata changed and got broken or sata_nv wasn't adopted for that change. HTH, -- (°= =°) //\ Prakash Punnoor /\\ V_/ \_V
