Or so it seems. If I do a make install in=20
/usr/ports/emulators/linux_base, panic happens. Alas, since my first=20
panic yesterday was KSE and was during portupgrade and I have no=20
linux_base presently installed, I suspect this is what caused that first =
panic.
Julian, since I now have a _reproducible_ KSE panic... what do you want=20
me to do? :-)
New backtrace, for your delight and enjoyment.
