nfs uvm_pagegetdirty panic

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

With Tuesday 4th February 9.99.45/amd64 source, I just got a:

System panicked: kernel diagnostic assertion "uobj == NULL || !UVM_OBJ_IS_CLEAN(uobjpage->uobject) || uvm_pagegetdirty(uobjpage) == UVM_PAGE_STATUS_CLEAN" failed: file "/usr/src/sys/uvm/uvm_fault.c", line 1754 

while copying a file from a NTFS partition on an external usb3 drive to
an NFS partition.

Side question: as this is running generic, I should be able to make use
of netbsd-GENERIC.symbols.gz - how do I do that?


Cheers,

Patrick
