Hi My old BeagleBoard Rev C2 stopped booting properly. Booting stops "Waiting for root device /dev/mmcblk0p2..." but goes forward if I feed e.g. ENTER over serial and have to press it through almost the whole userspace booting. At some point during process it seems to start working. Perhaps userspace fires some timer etc? I bisected the issue into commit 6cfcd5563b4f ("clocksource/drivers/timer-ti-dm: Fix suspend and resume for am3 and am4"). I used omap2plus_defconfig. # cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 3 (v7l) BogoMIPS : 594.73 Features : half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpd32 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x1 CPU part : 0xc08 CPU revision : 3 Hardware : Generic OMAP3-GP (Flattened Device Tree) Revision : 0000 Serial : 0000000000000000 Jarkko
