Hello, I originally posted about my problem on the Ubuntu forums ( http://ubuntuforums.org/showthread.php?t=673729 ). Having received not a single reply, I decided to give it a shot here. Also, I've been googling for a few evenings now and I cannot find any clear solution to this. :( First, here's what I'm using: Mythbuntu 7.10 Gutsy Biostar TF7050-M2 motherboard (with latest BIOS) AMD Athlon 64 X2 4400+ Brisbane Seagate Barracuda 500GB SATA2 2 GB RAM When I suspend (S3), it seems to work okay. Computer goes to sleep and I don't hear any fans or the hard drive, and the screen goes blank. When I resume, it *seems* wake up okay, until, I think, it tries to wake up the hard drive. Then all I get on the screen are errors like these: ata1 soft reset failed ata1 COMRESET failed device sda5 XFS metadata write error block <bunch of numbers> Buffer I/O error on device sda1, logical block <some number> Remounting filesystem read-only All I see are error messages like above scrolling... it doesn't seem to stop until I poweroff the computer, wait a few seconds, then poweron and it boots normally. Seems to me that the computer is unable to wake up the hard drive from its beauty sleep. :-/ I enabled/uncommented the following two lines in "/etc/default/acpi-support": DISABLE_DMA=true RESET_DRIVE=true ...but the problem persists. Do I need to modify something else in the acpi-support file? Then I tried to follow the instructions on this page ( http://zechs.dyndns.org/wordpress/?p=234 ) to get s2both and s2disk to work. When I tried Suspend, nothing seemed to happen at first. I was still seeing the desktop environment on the screen, the mouse cursor was still moving. I could still click on buttons and icons, however it would have no effect. No program would start. So I rebooted. What followed is one of the worst hard drive problem I've ever saw! It said that /dev/sda1 has way too many errors and that it'll only mount read-only so that I can run fsck manually. Then it gave me a root shell prompt. I ran fsck, there were many many inode and block errors about this and that. I was feeling pretty bummed out so I just answer 'y' when it would ask me if I wanted to fix the problem. The computer then rebooted again, and everything seemed to run normally. I tried all different programs and things (to see if any important files had been damaged), but everything looks okay. (Phew?) I still can't seem to get suspend to work though... which is a pain because I want to make the computer suspend to ram when I press the power button of my remote. :-| Guillaume - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
