Dear Rafael J. Wysocki,

I tested vanilla 2.6.33.2 and 2.6.34-rc3-git10, and unfortunately
both of them *have* this issue. So it looks like the issue has not
been resolved yet. Please keep this regression in the list of known
regressions.

Just to let you know: I am currently running 2.6.33.2 with the above-
mentioned commit reverted, and hibernate-thaw cycles work properly.

Regards,

M. Vefa Bicakci
