Hi Meelis, I think I know what's going on...

There was some bug in there which led to a crash. It was fixed later on. So, rc2 is probably bad, but this is not the main reason why your machine dies at the stage you report here... > 4.9.0-rc5-00297-g20afa6e, they both crash on boot like that. rc5 should be more OK, but just last night we fixed some more problems: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3ad0e83cf86bcaeb6ca3c37060a3ce866b25fb42 So, if you try, please update to latest git head now. > Hardware seems fine, I can boot kernels up to 4.8 without problems. > ... > HARD Booted. > palo ipl 1.95 portage@a500 Thu Jul 7 15:40:10 EEST 2016 > > Partition Start(MB) End(MB) Id Type > 1 1 32 f0 Palo > 2 33 224 83 ext2 > 3 225 31696 83 ext2 > 4 31697 34732 83 ext2 > > PALO(F0) partition contains: You sadly didn't included the PALO segment list here. I think this is your main problem. Probably you have quite some modules built-in, and your kernel got bigger than before and as such it triggers an old bug in the palo boot loader. Please read this palo commit message which explains it: https://git.kernel.org/cgit/linux/kernel/git/deller/palo.git/commit/?id=70bd7a9a41e318c0575755a78c4d18ad97495c47 I think those steps should fix your problem: 1. Boot into a functional kernel (e.g. v4.8) 2. Update your palo boot loader: https://git.kernel.org/cgit/linux/kernel/git/deller/palo.git/ You should build palo 1.96, and then *install* it into your palo boot partition: run "palo -v" once. 3. Pull and build Linus' latest git tree to get latest parisc fixes 4. boot again, palo should report version 1.96 and it should start your new kernel.
