Yeah, it's not working for me: > losetup /dev/loop0 > loop: can't open device /dev/loop0: No such device or address It's probably a build thing. Probably the config changed since 2.6.22... Yup. In additon to CONFIG_BLOCK I now have to enable CONFIG_BLK_DEV in order to enable CONFIG_BLK_DEV_LOOP. Why on EARTH did this subsystem develop two redundant guard symbols? Is there ever a reason to have the block layer enabled but no block devices? (And while we're at it, I don't suppose there's any way to get a list of the module names that are statically linked into the kernel? /proc/modules only shows you the dynamically linked ones...) That's interesting: > root@(none):/sys# exit > Kernel panic - not syncing: Attempted to kill init! > Segmentation fault (core dumped) UML now segfaults on a panic? Anyway, this was "upgrading to 2.6.23-rc3" breakage, not UML specific...
