Hi...
I have a shiny new Haswell notebook (Lenovo T440s), where with 3.11 processor power management didn't work, so I got 3.12-rc5 installed. Worked fine for a few days, then today it no longer boots and inspection yields...

:-(
In order to figure out the reason for this, can you kernel guys maybe a) tell me what is that datastructure? b) can power management be buggy to cause this - I played with powertop tuneables approximately while this happened?
...and point me to a recovery tool/doc for finding the partitions again, "testdisk" tool only found 1 of 3, the least important one at the beginning of disk but not the rest :-(
Thank you for any pointers/help!
