Subject: BUG() on apm resume in 2.6.18-rc2

After suspending to ram and then resuming, I'm getting the following on
2.6.18-rc2.  I also checked the latest git (54721324...) with the same
results.  The last that I know was OK was 2.6.17.

Let me know if any more information would be useful.

Copied by hand as fast as I could type, so there are probably typos....
