"diagnostic assertion "uvm_page_locked_p(pg)" failed"

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
I got this on a netbsd-5 host:
panic: kernel diagnostic assertion "uvm_page_locked_p(pg)" failed: file 
"/dsk/l1/misc/bouyer/netbsd-6/src/sys/arch/x86/x86/pmap.c", line 3326

There may have been an I/O error from the underlying device.
Does it ring a bell to someone ?
