I encounter the following unexpected behavior - On any kernel that I compile with IPv4 support, the kernel will stop intializing drivers after loading IPv4 support. The last message I see from the kernel is: NET: Registered protocol family 2 Compiling with debug allows me to single-step through the kernel. I've traced execution from inet_init(), to synchronize_net(), to synchronize_kernel(), to a call to wait_for_completion(), to switch_to_tt(), after which the kernel spends all its time in the idle loop. This happens whether I'm using SKAS or TT mode. Host kernel is 2.6.1 with Stephen William's 2.6.1 SKAS patch (thanks Stephen). Guest kernel is 2.6.1 with the latest patch from Sourceforge (January 15th), without modules, and with nearly everything disabled at compile except core functionality and IPv4. I've tried to find similar cases in the FAQ's and the list archives, but I'm not seeing anything. It seems like the kernel is waiting for an event related to IPv4 initialization that it never gets, but I'm not familiar enough with the kernel proper to know what that might be. Does anyone have any ideas?
