Any news on this? As noted previously, I am not able to reproduce the issue
you are seeing currently, can you give DEBUG_LL a shot?

Yeah I just bisected it, it was caused by this:

     arm: config: omap2plus_defconfig: switch over to LZMA compression

     LZMA compression makes about 33% smaller zImage
     with just a slight extra decompression time.

     Before this patch, zImage built with o2+_dc
     is 4.5MiB and after it's about 3.3MiB.

and the timeouts on the testbed being set to fail if a kernel takes longer
than five seconds to start.  Seems that the part about a "slight extra
decompression time" probably only applies to relatively recent chips.

Oh, so this explains why I was thinking it took very long time to boot the recent kernels also. The boot lag is clearly noticeable without any measurement. I wonder if we should probably revert this patch.
