My first instinct was to boot from the UBCD, which worked fine, but when I tried to boot PartedMagic, it Kernel Panicked on me, citing Not Enough Memory and No Killable Processes (Which is ridiculous, it's got 2048MB).
Looks something like this (copied by hand to this other computer, possibly with typos):

Like I said, there is more than enough memory, and the very same CD worked flawlessly just the day before. So I try again, with different settings, but all with the same approximate result. I try another copy of the CD, but to no avail. Finally I try an older copy, UBCD 5.0.1 with PM 4.1 and that worked perfectly!
What I gather so far is: The problem I had with the hdd was some kind of infinite-loop-of-extended-partitions, which could be a potential infinite-memory-leak. If I disconnect the misbehaving hdd or attach another one, everything works fine. I also note that the UBCD 5.1.1 comes with PM 6.6, with the 3.0 kernel, and that the UBCD 5.0.1 has the earlier 4.1 version of PM with the 2.6.32.11 kernel. This might(?) be the important difference. I later downloaded PM 2011-12-30, and the problem persists there and on every other LiveCD i can dig up with Kernel >3.0.
I don't actually need any help with this, i'm just writing to notify you guys of a potential problem. I still have the hdd around and can reproduce the problem anytime if you'd like me to try something out.
Thanks for an amazing tool! Keep up the good work!
[I first posted about this in the UBCD support forum, but was kindly pointed in this direction.]
