I enabled DDB in the kernel ("options DDB") in order to prevent the reboot and learned that the VirtualBox kernel module was causing the hold-up (I use VirtualBox very often, so I load the module at start-up). I'd forgotten to *rebuild the module after updating the kernel.* I feel foolish for having forgotten that---I've been using VirtualBox for years---but all is well now. Thanks for the pointers, and sorry for cluttering the list with such an inane issue. The quote in my signature seems fitting in this case. Anyway, take care, all. - Brandon -- =========================================== :: Brandon Wandersee :: :: brandon.wandersee@zoho.com :: =========================================== "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools." - Douglas Adams ===========================================
