The problem is likely because an 8.0 kernel is simply larger than a 4.11 kernel. 4.11's loader would have had the same issue. The problem (as it were), is that we expect to be able to load the kernel + modules into one contiguous chunk of RAM, starting at 4MB (PAE and amd64 kernels start at 2MB). > Best regards > Carsten Bäcker > > > On Sunday 06 December 2009 12:16:36 am Hiroki Sato wrote: > > Hiroki Sato<h...@freebsd.org> wrote > > in<20091205.184250.201700943....@allbsd.org>: > > > > hr> A summary so far is: > > hr> > > hr> 1) a<8MB 7.1R kernel + stock 8.0R loader > > hr> 2a) a>8MB 8.0R kernel + stock 8.0R loader > > hr> 2b) a>8MB 8.0R kernel + 8.0R loader with LOADER_NO_GPT_SUPPORT=yes > > hr> 2c) a>8MB 8.0R kernel + loader with your patch > > hr> 3a) a<8MB 8.0R kernel + stock 8.0R loader > > hr> 3b) a<8MB 8.0R kernel + 8.0R loader with LOADER_NO_GPT_SUPPORT=yes > > hr> 3c) a<8MB 8.0R kernel + loader with your patch > > > > Grr, I double-checked how it got stuck, then I found the console > > redirect was disabled because of an old device.hints.
