--0016e6509fd8c74ab104afd0aefd Content-Type: text/plain; charset=ISO-8859-1 Hi, I'm facing a kernel panic at vm_page_wire(). Page is locked with vm_page_lock() yet i get the following panic panic: mutex page lock not owned at /usr/src/sys/vm/vm_page:1845 Code sequence is as below vm_page_lock(pp); vm_page_lock_assert(pp, MA_OWNED); /* No panic here */ vm_page_wire(pp); /* Panic here for the same assertion as above, strange */ vm_page_unlock(pp); Kernel on the system is unchanged after install. The only thing which occurred out the way was that the first time install failed for checksum mismatch for src.txz. Also there were some SCSI errors/warnings with the CD drive during install. So the next time, i only installed the base and kernel and later unpacked src.txz under /usr/src . Could this lead to any issues ? Attached is a test module (vmtest) and the makefile used. Uname output from the system is FreeBSD scache 9.0-BETA3 FreeBSD 9.0-BETA3 #0: Sat Sep 24 21:31:28 UTC 2011 root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 Is there anything i'm doing wrong here ? Kindly help.
