A more precise way to state that would be "a regression in FreeBSD boot/loader". I think that you are referring to the issue that was fixed by r189017. It might be worthwhile investigating what was done in that revision and what happened in sys/boot code since then. One possibility is that your BIOS uses memory above 1MB for USB emulation, but doesn't mark that memory as used in system memory map. In that case that memory could be overwritten by the loader. If that's true then the blame is on the BIOS. Alternatively, our code might be parsing the system memory map incorrectly. But I am just making wild guesses here. -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
