git-bisect revealed this:

USB: fix ehci unlink regressions
The recent EHCI driver update to split the IAA watchdog timer out from the other timers made several things work better, but not everything; and it created a couple new issues in bugzilla. Ergo this patch:
- Handle a should-be-rare SMP race between the watchdog firing and (very late) IAA interrupts;
- Remove a shouldn't-have-been-added WARN_ON() test;
- Guard against one observed OOPS;
- If this watchdog fires during clean HC shutdown, it should act as a NOP instead of interfering with the shutdown sequence;
- Guard against silicon errata hypothesized by some vendors: * IAA status latch broken, but IAAD cleared OK; * IAAD wasn't cleared when IAA status got reported;
The WARN_ON is in bugzilla as 10168; the OOPS as 10078; these are both regressions.

For the linux-usb people: this commit breaks resume from suspend to RAM on my Mac mini Core Duo. It worked with 2.6.24, 2.6.25-rc5, and was broken since 2.6.25-rc6 (also with -rc7 and later). See http://lkml.org/lkml/2008/3/20/23 for more information.
