I don't think I removed 8M of config options, but who > knows. I just enabled CONFIG_DEBUG_LOCKDEP=y and CONFIG_DEBUG_ATOMIC_SLEEP=y and it did not boot again. Sizes are much smaller than kexec's image-size parameter (26214400 - 25MB): $ ls -l arch/arm/boot/Image -rwxr-xr-x 1 sre sre 17768448 Jul 12 00:38 arch/arm/boot/Image Then I increased image-size parameter to 33554432 (32MB) and it boots again. So looks like it is a size problem. I wonder what size this is about, though. -- Sebastian
