The only problem is that with the debugging options the system is unbeleavable slow. As an example the clock swi takes about 20% CPU... I added the following: options KTR options KTR_EXTEND options KTR_ENTRIES=1024 options KTR_COMPILE=0x3fffff options KTR_MASK=0x201208 options KTR_CPUMASK=0x3 #options KTR_VERBOSE options MUTEX_DEBUG options WITNESS #options WITNESS_DDB options WITNESS_SKIPSPIN options DIAGNOSTIC options INVARIANTS options INVARIANT_SUPPORT What are the current recomended options? Hopefully I can remove some of them without loosing too much information for the failure case. -- 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
