Hi Tejun, Will get more debugging info by setting up netconsole. Meanwhile, syslog did glean some important info, I think. Looks like, for some reason, after resume, device mapping for the hdd changes from sda to sdc. Please see logs below. For ease of troubleshooting, I re-installed the box with stock Fedora 13 x64 with no modifications except that dmcrypt is turned on for root and swap (so using Nouveau display drivers instead of Nvidia).
