Some context: i'm trying to collect a backtrace from my Amiga 1200 + Warp 1260[1] + flicker fixer that refuses to boot and shows a solid grey screen.
I've added some printk around init/main.c::start_kernel() and it *appears* to be hanging in "local_irq_enable();".
Doh, I missed this part. So it never gets to initcall_debug. Probably some of the Warp 1260 on-board hardware has its interrupt line asserted, causing an interrupt storm when Linux enables interrupts. Amiboot knows how to reset several boards to prevent this, but it doesn't support Warp 1260 yet. https://github.com/geertu/m68kboot/blob/master/common/amiga/linuxboot.c#L195 Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
