From: Adrian Chadd To: "freebsd-mips@freebsd.org" Content-Type: text/plain; charset=UTF-8 X-BeenThere: freebsd-mips@freebsd.org X-Mailman-Version: 2.1.20 Precedence: list List-Id: Porting FreeBSD to MIPS List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 02 Nov 2015 02:33:56 -0000 Hi, There are a couple of things that are broken on mips32 right now and I'm stretched pretty thin for time. I'd really appreciate it if someone could help by figuring out what's up. * If I use scp to copy something into a USB rootfs on my Carambola2, the whole system hangs. I can use ddb to break into things, but nothing obvious has shown up. The only two locks are a buflock and a vfslock - but I didn't get any LORs from Witness. * ddb "continue" and "step" no longer works. I don't know when it stopped working; I'd really appreciate some help figuring that out. I'm going to keep poking at some of the default tuning bits as well as performance/stability bits on ethernet and wifi. But having a working multi-user board and a working debugger would be really, really helpful. THanks! -adrian
