Comment 58 for bug 226279

I'm similar to the rest: -16 resumes quickly, -17 doesn't, and neither does -19. However, -19 seems to recover in around one-third of the time that -17 takes, but I've only performed three trials on the new one.

Blacklisting ehci_hcd doesn't fix it, although both pm_trace and dmesg point to it being the culprit, as 1d.7 is the only EHCI controller in the system. Even removing all USB-related modules doesn't help.
