I have the same problem. My Kernel is basicly a GENERIC with SMP and ULE added (4BSD removed). ([mhettwer@siteop-8] <~>)$ uname -a FreeBSD siteop-8.mobile.rz 5.4-STABLE FreeBSD 5.4-STABLE #7: Wed May 11 12:03:35 CEST 2005 root@siteop-8.mobile.rz:/usr/src/sys/i386/compile/SITEOP-8 i386 > This is very big problem for people who want use mysql_server on SMP > machines... indeed. The MySQL server won't start and is not killable. I had to switch back to SCHED_4BSD :-/ I would be available for testing packages, as this machine is not in production. it's a dual xeon 2,8 ... you can find detailed information about it at: http://unixoid.de/freebsd/dmesg.xeon :) best regards, Marian
