Re: Can't get a Linux 3.6-rc zImage smaller than 2MB

Months passed and I finally made progress.

I managed to compile and boot a 3.7.10 kernel on SS4000-E.

I basically went through the ordeal of doing the compile on the box itself, instead of cross-compiling on an x86 VM,

Took ages, but it worked.

One thing I noticed is that flash-kernel refuses to flash if the kernel image does not end with iop32x, like /boot/vmlinuz-3.7.10-iop32x

I had too look at the flash-kernel source to figure it was just being fussy about a file name!

Anyway to bring the system up to speed from Debian's 3.2 kernel I'm going to compile my own e2fstools and iproute2 as I need them for experiments with new ext4 features and want to use fq_codel on network interface.

Is there anything else you suggest that I recompile from things like util-linux, etc?

Best regards,

Maciej
