I know it won't make much difference now, but could I generally please advocate the idea that this message: "Oct 7 18:36:46 localhost kernel: Debug: sleeping function called from invalid context at mm/slab.c:2082" Is utterly useless as an error message? It doesn't tell us: * which kernel version you are using * what code you were running * whether you are using a tainted kernel * anything more than a BUG type line in a standard kernel file Jon. -- Kernelnewbies: Help each other learn about the Linux kernel.
