I’m running 11.3 swapless on a HP dv6z (AMD Turion dual-core processor, 3GB RAM, ATI Radeon HD 3200 graphics), customized by replacing the original hard drive with an Intel 40 GB X25-V SSD.
About 2 out of 3 times the suspend to RAM and resume work fine, taking a couple of seconds to suspend and resuming almost instantaneously. The other times, suspend seems to hang for about 30 seconds or so with the monitor displaying a console login (same as I see briefly when a suspend works). The display eventually shuts off, and the light is blinking on/off as in a normal suspend, but when I resume I’m unable to login. The message I get when I try to login is “Cannot unlock the session because the authentication system failed to work, you must kill kscreenlocker (pid 12,139) manually”; if I go to a console screen and try to login as root to do the kill I get “end-request: I/O error, dev sda sector …” repeated many times, and cannot login that way, either.
pm-suspend.log shows the hang-up occurring at the same point each time, after all the sleep.d operations. Here’s a sample:

If I try to resume after this nothing more is added to the log. On a resume from a successful suspend, the log continues on:
