I was sort of hoping to drag a more experienced kernel hacker than I into helping fix this :-) The trace should be read from the bottom up to find out what lead to the crash. The top function is the one in which the panic occured. A wild guess is that the `xfer' pointer (arg 2) passed to uhci_idone is pointing to invalid memory. Or maybe the whole `ii' pointer is NULL. Do you have INVARIANTS in your kernel config? How about DIAGNOSTIC? If not, maybe try options DIAGNOSTIC and recompile. See if you get a different panic. I'm CC'ing this to -hackers. -- Josh > > Thanks > Michael > > > On Wed, 2003-07-09 at 21:48, Michael E.
