https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227116 --- Comment #18 from Daniel Kolesa <daniel@octaforge.org> --- Created attachment 192014 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=192014&action=edit patched kernel I built the kernel on my server and replaced it in the installer image, but it still fails at the same place. Backtrace photo in attachment, kgdb here: (kgdb) list *uma_startup_count+0xd6 0xffffffff80e3e7b6 is in uma_startup_count (/usr/src/sys/vm/uma_core.c:1827). 1822 /* Memory for the rest of startup zones, UMA and VM, ... */ 1823 if (roundup2(zsize, UMA_BOOT_ALIGN) > UMA_SLAB_SIZE) 1824 pages += (zones + vm_zones) * 1825 howmany(roundup2(zsize, UMA_BOOT_ALIGN), UMA_SLAB_SIZE); 1826 else 1827 pages += howmany(zones, 1828 UMA_SLAB_SPACE / roundup2(zsize, UMA_BOOT_ALIGN)); 1829 1830 /* ... and their kegs. Note that zone of zones allocates a keg! */ 1831 pages += howmany(zones + 1, As you can see from the source, it still fails in the very same place, and you can also see how I patched it. You can also see from the uname in the photo that it is indeed the patched kernel. -- You are receiving this mail because: You are the assignee for the bug.help
