platform : i486-linux-glibc2, kernel 2.1.106ac2 compiled with gcc-2.8.1.
I get oops when trying umdos filesystem (mount-2.8, umsdos support in the
non-SMP kernel) :
*** checking dentry: --linux-.---
iput: device 03:01 inode 8623 still has aliases!
creat_dentry: WARNING: NO parent! faking! beware !

Any idea ?
OTOH, how could I translate this to a list of processes/dissassembled
codes ?

Thanks
