Should the kirkwood kernel have "Breaks: u-boot (<< 2011.12-3)" to encourage people to update their bootloader when they are lucky enough to be on a machine where the bootloader is installed through the package management system? Should there be a flavor-specific NEWS.Debian.gz to warn sysadmins about the problem? (I think "yes".) Should the kirkwood flavor disable CONFIG_ARM_PATCH_PHYS_VIRT? (My hunch is "no, it shouldn't", but that possibility's available if we wanted to return to the behavior of the good old days of 3.1.y.) Context: [1] | Okay, so this should mean that the kernel's own decompressor has run, | which should turn on/off the mmu and caches, cleaning and invalidating | them, which will take the boot loader completely out of the picture at | this stage. Could the decompressor disable the L2 cache itself as a workaround? Given that no one with the right familiarity with the decompressor code has volunteered to do that, I'd suggest: - teaching u-boot in stable to follow the boot protocol correctly - adding a NEWS.Debian.gz in the kernel package to warn people - mentioning this in the armel variant of the wheezy release notes.
