On return, copied and stripped kernel, then did 'make install' which resulted in a panic. As I had just clobbered the unstripped version of the old kernel, I was not able to get any meaningful information from kgdb. However, I managed to note the following while in DDB:- panic: vm_page_free: pindex(0), busy(0), PG_BUSY(0), hold(21) trace: _panic _vm_page_freechk_and_unqueue _vm_page_free_zero _pmap_release _vmspace_free _cpu_wait _wait1 _wait4 _syscall _Xsyscall syscall 7 >How-To-Repeat: >Fix: >Audit-Trail: >Unformatted:
