Hello samba team,
hi there when I try to copy, move to the Samba server it generates a
nice kernel bug. I'm currently running samba-2.0.7-pre3 but
samba-2.0.6 also has this problem. Reading files off the vfat share
works fine. Also writing small ascii and binary files works, but if
the binary file is about 3 Mb or larger.
I'm currently running Linux-2.3.99-pre4 and samba worked fine with
2.2.14. (linux 2.3.49 and 2.3.50 also have this problem) The problem
is that since that kernel the /usr/src/linux/fs/fat/file.c has
changed
a lot.
Extra info: Running samba to access vfat share with vfat compiled
into the kernel.
I don't know if this is a problem caused by samba or
the experimental kernel. So I would like to contact both the samba
and the kernel development team, and hopefully we'll get this bug
solved.
Can someone tell me what the problem is ?
Thanx ..
