X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 05 Nov 2008 09:29:03 -0000 I observe the symptoms that are the same as described here only with 7-BETA2 (amd64): http://lists.freebsd.org/pipermail/freebsd-hackers/2006-March/015736.html If ukbd is both in kernel and is loaded via module then kernel boot locks up. I have a custom kernel without USB in it (everything is loaded through modules), but sometimes I need to boot GENERIC. So the issue occurs with GENERIC. Unfortunately, loader.conf is not per kernel (and I haven't heard about kernel conditionals in it). Does anybody have any insights on this? In the referred thread John Baldwin mentioned some "edge cases", but nothing concrete. I think that such behavior is not satisfactory. I am willing to help with researching this, but I need some starting pointers. Unfortunately, no serial console. P.S. This is legacy-free machine, no PS/2 port (but I am not sure about actual keyboard controller in hardware). BIOS has "USB Legacy" enabled. GENERIC, obviously, has atkbd and kbdmux in it. -- Andriy Gapon
