It quacks && stinks like a duck, Poul. It's a dead duck. This panic certainly occurs under no other filesystem I can find. But I'll leave it to you to decide things are peachy. I say they isn't. I sure as hell am not going to enable using mdconfig(8) as a replacement for MFS. It's only because I really want to see DEVFS move forward that I'm seething with amusement instead of pissing rage over our usual moe, larry && curly antics... :-)... > > Considering the state of -current, I'm not sure I see your trace > as an obvious indication of anything, but if I can reproduce it > tonight I'll try to see what I can find. > > What's "lmdd" ? Larry McVoy's dd- out of lmbench. I find it handier to use than dd because I don't have to give it a source of /dev/zero- and it has all sorts of bells and whistles- hell, it's even good at doing memory bandwidth testing: 2x200MHz older PPro: remler.nas.nasa.gov > lmdd 255370.19 MB in 3.62 seconds (70578.0187 MB/sec) 170Mhz Ultra1 Solaris: sun520 > lmdd ^C157099.02 MB in 2.79 seconds (56356.6797 MB/sec) 333 MHz Alpha 600 (NetBSD) poseur.nas.nasa.gov > lmdd ^C296471.36 MB in 2.98 seconds (99601.9453 MB/sec) and so on... At any rate- nothing special about it. I was just using it to see how quick a fill of this new MFS replacment would take.
