Hey, absolutely! I'm enjoying myself. :-) Well, I've managed to get it to die in front of me this time. You'll have to tell me how to get it do do a backtrace -- I'm leaving it at the debugger prompt expressly for that purpose. Transcribed by hand below is what I see leading up to the crash. I was on a fresh boot trying to do a make clean under x11-wm/xfce4. I had built it on the previous boot and froze it remotely when I tried to do a make clean (xfce4 works great -- no changes to the port). Here is what I see (first two sets repeated multiple times, xxxxx represents various lba, ad0s5 is root): ad0: timeout waiting to issue command ad0: error issueing WRITE_MUL command ad0: timeout waiting to issue command ad0: error issueing WRITE_MUL command ad0: timeout waiting to issue command ad0: error issueing WRITE_MUL command ad0: timeout waiting to issue command ad0: error issueing WRITE_MUL command swap_pager: I/O error - pageout failed: blkno xxxxx, size 65536, error 5 swap_pager: I/O error - pageout failed: blkno xxxxx, size 65536, error 5 swap_pager: I/O error - pageout failed: blkno xxxxx, size 65536, error 5 swap_pager: I/O error - pageout failed: blkno xxxxx, size 65536, error 5 g_vfs_done():ad0s5[WRITE(offset=6160384, length=2048)]error = 5 init died (signal 4, exit 0) panic: Going nowhere without my init!
