No, but that's what broken code often does. :( -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.

Taking your suggestion I zeroed out the CF card, then used fdisk and newfs_msdos to get it in working order again. I've been testing it over the past week and have had no problems since. Thanks for the pointer.

It shouldn't matter, but that makes me nervous (not that I think it has anything to do with your problem.) It would appear that your da0s1 has data at the front that looks like an MBR and GEOM is attaching to it. I'm not sure what the best solution to that problem is. Probably a reformat. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.

Unfortunately not. I was able, having mounted the filesystem with no synchronization options, to copy 171MiB of data onto it and unmount. However when I re-mounted it with the same options and tried to copy 71MiB more, it again froze midway through. Everything else (X11, sound, printing, input) seems to be working perfectly with 5.4, but I did notice something new and strange with regard to umass.
