Yes, it is the problem. After I reversed the order in initrd, the "device not accepting" error no longer appears (when I shutdown the box and then reboot).

When I start the hibernation using 'swsusp', I see the following messages on the console: [ I cannot paste the contents to a file when this happens, so sending excerpts..] [I have also enabled the PM debug messages in the config] " Shrinking memory swsusp: Need to copy 108345 pages swsusp: critical region/: done (108345 pages copied) swsusp: Restoring Highmem PCI: Enabling device 0000:00:1d.7 (0000 -> 0002) usb usb1: root hub lost power or was reset usbdev1.2_ep00: PM: resume from 0, parent 1-1 still 1 [followed by the similar usb messages, but for different hubs] " Today, I decided to wait for some time after seeing these messages. Then the console started spitting the following messages: " sd 0:0:0:0: timing out command, waited 360s end_request: I/O error, dev sda, sector 152121693 Read-error on swap-device (253:1:24) " So, it may not really be the 'usb' problem, but rather something to do with this 'sd' driver or even the sata driver.? Also, when I try to power down the box when this happens, I also see an ACPI error: ACPI error (evevent-0314): No installed handler for fixed event [00000002] [20060707] Perhaps, I should forward all this to the 'linux-kernel' list?
