Hello everyone! Am Donnerstag, 23. Januar 2014, 10:31:59 schrieb Émeric MASCHINO: > Did you compile kernel with -O2 or -O1 optimization? Thanks for that hint! -O1 boots with output (the default is -O2 and does not work, and -Os or CONFIG_CC_OPTIMIZE_FOR_SIZE does not work either). I get an oops, though: [ 56.305585] Unable to handle kernel NULL pointer dereference (address 000000000000003c) [ 56.305842] modprobe[896]: Oops 8821862825984 [1] Logs attached. The same config worked with gcc-4.5.4. I assume it is best to first make -O1 work and then progress to -O2 later? --Dennis
