That doesn't interest me. I suspect that is the right solution - I've been trying to get 4.19 to boot on my RPC and it's proving very difficult for several reasons, not limited to the HDD seeming to be throwing the odd disk error, as well as the kernel being rather large (a 4.19 kernel is 2.7M compressed as opposed to 2.6.29 being 1.2M compressed for the equivalent configuration.) Given that memory on the RPC is not contiguous, that probably means an uncompressed kernel overflows the size of the first memory bank, so there's probably no hope for modern kernels to boot on the machine. The EBSA110 is probably in a similar boat - I don't remember whether it had 16MB or 32MB as the maximal amount of memory, but memory was getting tight with some kernels even running a minimalist userspace. So, it's probably time to say goodbyte to the kernel support for these platforms. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
