ls -laR & find running at the same time? How much memory does the linux
box have and how much else is running on it? Maybe there is some low
memory condition that smbfs doesn't handle. 10 or 100 Mbps network?
How much data is there on the machine? Does it only happen on large trees
or is a small testcase such as a kernel source tree enough to cause the
oops?
Attached is a patch vs 2.2.14 (it will not apply cleanly to 2.2.16 or
17-pre, but if you want to test those you can apply the changes "by hand"
or ask me and I'll make a new patch).
It will produce output like this (long lines broken). This is a complete
find-run vs an NT4.
smb_read_super: allocating packet @ c8836000 size: 4096
smb_decode_long_dirent: new p pointer: c8836f74, (+104)
server->packet: 4096@c8836000
smb_decode_long_dirent: new p pointer: c8836f74, (+0)
server->packet: 4096@c8836000
smb_decode_long_dirent: new p pointer: c8836f78, (+112)
server->packet: 4096@c8836000
smb_decode_long_dirent: new p pointer: c8836f78, (+0)
server->packet: 4096@c8836000
smb_receive: allocating packet @ c8838000 size: 8192
It will output a "new p pointer" when it comes within 200 bytes of the end
of buffer and also print all allocations of "server->packet".
new p pointer: c8836f78, (+112) server->packet: 4096@c8836000
^^^^^^^^ ^^^^ ^^^^^^^^^^^^^
the next dir entry (the value it oopsed on)
how long one entry is (+0 on last entry?)
size and address of the buffer
It also tries to print an error message if the 'p' pointer is moved to
point outside the buffer and there are more entries to be read.

Why can't you test on the machine that was reinstalled? Not that it
matters as long as you can produce more oopses.
