Hi, i tried to install FBSD 9.0 beta 1. Booting the install-cd stopped with a kernel panic: panic: _mtx_lock_sleep: recursed on non-recursive mutex arcmsr Q buffer lock @ /usr/src/sys/dev/arcmsr/arcmsr.c:2093 A screenshot from the panic can be found here: http://ugrohnwaldt.web02.lando.us/FBSD/arcmsr.png Chers, Uwe
