I started using the min_power ALPM setting on my ThinkPad to save power (which works great, thanks!) but it causes a small problem. When the machine resumes from suspend-to-ram it hangs for about 10s and then prints this on the console: ata1: COMRESET failed (errno=-16) It then proceeds normally. The full messages are: ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: configured for UDMA/100 ata1: failed to recover some devices, retrying in 5 secs ata1: soft resetting link ata1: SATA link down (SStatus 611 SControl 300) ata1: failed to recover some devices, retrying in 5 secs ata1: hard resetting link ata1: port is slow to respond, please be patient (Status 0x80) ata1: COMRESET failed (errno=-16) ata1: hard resetting link ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) After which point the machine works normally. The SATA controller is an Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller (rev 03) and the SATA target is a SAMSUNG MCBQE32G Rev: PS10. The kernel is 2.6.24. I haven't tried anything newer. If the ALPM setting is left at its default of max_performance then resume from suspend is instant. Is there any way to work around this? ALPM is worth a solid 30 minutes of extra battery life, so obviously I'd like to use it. If nothing else, it might be helpful to have a module parameter to shorten the timeout on known-working hardware. -jwb -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
