Also, the system hangs often (without pan= ic) during the boot process at the "Setting hostname: icarus." level. Becau= se I had absolutely no time, I couldn't learn to use the kernel debugger be= fore.=20 icarus# uname -a FreeBSD icarus 5.4-STABLE FreeBSD 5.4-STABLE #0: Sun Jul 3 15:14:13 CEST = 2005 cedric@icarus:/usr/obj/usr/src/sys/ICARUS i386 Sources are from July, 1 debug.mpsafenet: 1 After compiling the kernel with debug options, I get the following during t= he boot process: Setting hostname: icarus. lock order reversal 1st 0xc2cd4c6c ath0 (network driver) @ /usr/src/sys/dev/ath/if_ath.c:893 2nd 0xc30583c8 user map (user map) @ /usr/src/sys/vm/vm_map.c:2998 I suppose this explains the occasional hangups during the boot process?
