Hi
I use UMSDOS for using a part of my msdos-space for linux.
Since 1.3.31, almost every attempt to move a file to a different
directory on the same filesystem results in the following:
<1>Unable to handle kernel NULL pointer dereference at virtual address c0000004
<1>current->tss.cr3 = 00fec000, %cr3 = 00fec000
<1>*pde = 00102067
<1>*pte = 00000027

(ksymoops doesn't compile for me -- what/where is libiostream, fstream.h,
iomanip.h ?)
I don't have the system.map anymore but i checked it at a prevous Oops:
rename_diff_dir
msdos_scan
msdos_rename
umsdos_rename_f
UMSDOS_rename
do_rename
sys_rename
system_call
I tried with 1.3.34, same thing. Stepped back to 1.3.30: everything is
alright. But I can't find anything for (u)msdos in the patches...
