Hi all. I have been happily using Linux 2.6.22.1 for ages on PNX8550 (STB810). I have recently decided to step up and move onto Linux 2.6.24 series. However I am not getting very far. :-( It seems that all the clock stuff has changed again (since 2.6.22.1) and this is causing issues. The board crashes as soon as local_irq_enable is called in main.c I was wondering if anyone out there might also be running on an STB810/JBS PNX8550 based system and have any ideas as to why I am crashing. I know that PNX8550 does not enable the R4K Clock source stuff as the chip is a bit 'special' and requires the two timers to be used instead of one. As far as I can see I think my interrupts are not being setup. Any help, ideas etc are appreciated. Daniel Laird
