i used ramMonitor to tftp the kernel info flash. using the read command i checked to make sure it was all there. upon booting the kernel via copy from flash same result. works for small kernels not for large. gziped kernels did the same thing. in the compressed state they were less than 2.6M, but never worked if they were larger than 2.6 when uncompressed. so.. it seems like a freebsd problem not the boot loader.
