Hi all, Many people are reporting that suspend to RAM is not working as expected on at least various Vaio laptops : it takes very long (about 40 seconds) to come back from suspend.
On those laptops, the recipe to make S3 work is about like this : 1. Try to use acpi_sleep=s3_bios, napic, nolapic kernel boot options 2. Use a hard drive reset trick to be able to come back from suspend (i. e. hdparm -w /dev/hda) There is a good description of this on this page : http://www.sr.bham.ac.uk/~adf/debian-on-sony.html But after waking up, the console outputs : hda: lost interrupt hda: dma_timer_expiry: dma status == 0x21 Those messages repeat and there are also DriveSeekError messages. Does anybody if this is hardware related? Or is this a kernel bug? Thanks in advance for any clue on this. Alexandre
