Hey Geoff, thanks for your time and the clarification!
My firmware is downgradable, this should be possible because it got SS patches. Could be these are from you, so I could go back in fact to 3.15 and try the otheros.bld workaround. Thing is, I don't know if I can split my HDD to use my 110GB Linux; isn't it the case that normal OtherOS only grants you 20GB for Linux? That's the only thing that's holding me back, this way I could even use normal Debian. I use an old and still working FAT model. The 1400 is a tool model which I don't own. I don't like what I read about the ABI breakage stuff, to be honest. Especially the second link describes pretty well what happens on my machine. So, current status here is to upgrade to 3.15 kernels only, I think it doesn't make sense to try higher versions at the moment. Is it really "only" a kexec problem? Or something deeper, more difficult? I can try to help but I'm pretty new in this PS3 PowerPC Linux stuff. Using OtherOS++ was a coincidence. I found this special PUP which splits the HDD in half for Linux and GameOS. This was exactly what I wanted, so I stuck with it. :-) Finding PUPs today which provide Linux options is nearly impossible. I'm not a fan of "Rebug" either, don't want/need it. But they had one firmware with OtherOS++ support which was taken down or whatever. It's just non-existent anymore. You don't know a community for OtherOS++ by chance? I found some forums online but most of them only care about pirated games (which doesn't interest me at this age anymore) and/or show posts which are highly outdated. It's pretty hard today to stick with this hardware. But I'm fascinated by the Cell BE and want to learn it. It became a little obsession. So even compiling a kernel on the PS3 doesn't bother me much, I go to work and when I come home the fresh *.deb packages are ready to install. :-D But I understand what you mean of course, will check out cross-compiling. Geoff, thanks again for your time and wisdom! All the best, Sascha Am 8.
