I have a largish FAT-32 partition in my fstab with noauto set. When I 
started my system today I was greeted with automatic filesystem check 
failure and the message mount_msdos : Can't allocate memory for FAT. 
Mounting the file system by hand works fine and passes a fsck. 
Coincidently or perhaps not, there were several USB issues at the same 
time, like two hubs not being activated and port failures. Do we still 
have contiguous kernel memory allocation issues?
