As far as I can tell, the beagle hang issue aries after this commit:

397f49cde4e75cf662a23814097db35f3e6c6b62 is first bad commit
commit 397f49cde4e75cf662a23814097db35f3e6c6b62
Author: Jouni Hogander <jouni.hogander@xxxxxxxxx>
Date:   Fri May 16 13:58:25 2008 +0300

    34XX: PM: Initial version of suspend and dynamic retention

    This is initial version of suspend and dynamic retention for
    34xx. Omap is tried to put to full retention on suspend and pm_idle.

Could someone please test and confirm if the previous commit works without a hang?
I waited for around 20 minutes and did not observe a hang.

These were the last two good commits I got from git-bisect.
# good: [1c66e10c850950a84da68cafb07022eab5e7eec0] 34XX: Suspend: Take suspend sram code from ti cdp kernel
git-bisect good 1c66e10c850950a84da68cafb07022eab5e7eec0
# good: [131ce2d1dd5081f97885419678a8b3211c7c2dee] 34XX: Add miscellaneous definitions related to 34xx

Anand
