I got a panic early in the boot which I asume is fixed with his commit: [...] isa_probe_children: probing PnP devices Timecounter "i8254" frequency 1193182 Hz Timecounter "alpha" frequency 500004746 Hz bpf: lo0 attached ../../kern/kern_synch.c:608: sleeping with "Giant" locked from ../../kern/init_main.c:392 witness_sleep Stopped at Debugger+0x2c: ldq ra,0(sp) <0xfffffc00006739f0> <ra=0xfffffc000054aee0,sp=0xfffffc00006739f0> -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
