during boot i get these errors

[1.572014] ata1: Softreset failed (device not ready)
[2.792017] ata3: Softreset failed (device not ready)
modprobe: FATAL: Could not load /lib/modules/2.6.28-11-generic/modules.dep: No such file or directory

Then Ubuntu successfully boots, so i dont know. Im hoping it has something to do with my suspend feature acting weird. I can suspend successfully the first time, then when i resume theres a plug icon in my tray and im unable to suspend again, and if i click on the plug and click suspend it says suspend is forbidden for some reason. Another weird side effect is if i log out after a resume from suspend where this plug is in my tray the system freezes up and a box comes up and says failed to initialize HAL! Ubuntu 8.10 works fine but a fresh install of 9.04 doesnt. Any help would be appreciated
