Comment(by nicolas.dufresne):
Few question to help debugging:
- Is it reproducable using Qi ?
- Will it come back to normal if you suspend again and wake it up ?
My own testing proved that a big difference between 2.6.24 and 2.6.29 is
that the new kernel can recover from WSOD by going back to resume an other
time. But I never identified why, and also I've never tested 2.6.29 with
U-Boot. Answer to does question may be the key of this long standing
enigma.
