The dentry list corruption could be caused by writing through a stray
pointer, so it's possible that a bug in ppp (or another module) could
show up in this way. The two oopses look like ascii data was written
over a pointer.
It might be helpful if the people who have gotten one of these
dentry-related oopses compared their configurations and the software in
use at or near the time of the problem. If we could see some common
usage it would help narrow the search for the cause.
