There it seems to be stuck and the last message printed is: [ 0.000000] Calibrating delay loop... Doing a manual bisect I can get the board to boot again when I revert the following commits from Linus master: 14070ade02cc378bc30dae383532768a94805988 - ARM: at91: fix new build errors c4b68520dc0ec96153bc0d87bca5ffba508edfcf - ARM: at91: add AIC5 support 4c6971a6debb340d487cf6189f15a1332702330f - ARM: at91: remove mach/irqs.h 8fe82a5550a8e97b3f59c74f994b88ed6b3544a3 - ARM: at91: sparse irq support 3e135466745a62b1814edef74c7b4a25e6bda707 - ARM: at91: at91 based machines specify their own irq handler at run time There may be some unnecessary reverts here but there are multiple build failures between the different commits (grrrrr) which makes it pain to filter it out. I suspect that right now all AT91 RM9200 machines are broken by these IRQ changes on AT91. regards Joachim Eastwood
