In my testing (another 12 hours of uptime, BTW), the three patches I am
using are:

ca109491f612aab5c8152207631c0444f63da97f
37810659ea7d9572c5ac284ade272f806ef8f788
a0a99b227da57f81319dd239bc4de811b0f530ec

I have not tried the other patches.

That said, I would not recommend just the three for -stable unless they
get a much wider amount of testing, on multiple platforms. I don't see
that as likely to happen, plus Peter says they are incomplete, so maybe it
is just best to recommend that 2.6.28 users getting crashes while using
HTB try these specific patches at first, and then the rest of the patches
if they do not work.

Thanks,
Chris
