Problem with USB flashdisk (used to work) and kernel dump on reboot

[Erich Hoover]

I'm getting some problems after all the recent development updates.

1) My usb flashdisk will no longer mount (it works in other computers 
and it used to work before the updates), it reports:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       or too many mounted file systems

2) When I try to reboot the kernel gets all the way shutdown until the 
very final reboot operation and then it dumps - is there a way I can get 
a log from this?  It looks like all logging has been disabled by the 
time the kernel gets to this point (especially since it's already 
unmounted by hard drive).

Running on an ASUS SK8N w/ an FX-53 under x86-64 mode.  Any help would 
be greatly appreciated.
