[SOLVED] TP X220: Can no longer pm-suspend; still can't pm-hibernate

view story

https://bbs.archlinux.org – Thanks!  That works perfectly.  I saw some threads from Ubuntu installs that suggested xhci_hcd might be the problem, but unloading that didn't solve it, and I didn't think to look at other modules.Is there a reason to prefer 'rmmod' over 'modprobe'?  (The man page just says "Most users will want to use modprobe with the -r option instead.")Do you have any idea why I would have been able to suspend before (without the 'resume' hook and without unloading iwlagn)?Is it correct for hibernate to behave as a reboot (passing through GR (HowTos)
