RE: [hpoj-devel] no end of trouble

[PASCHAL,DAVID (HP-Roseville,ex1) <dav...@hp...>]

Hi, Carlos.  The vast majority of the problems you described are due to
continuing incompatibilities between the kernel-mode drivers (ieee12844 and
ieee12844pp) and SMP.  I apologize for the inconvenience, and I'm working on
a long-term solution.  If you don't mind temporarily disabling SMP in the
meantime, then it will be much more stable.  Since you said scanning works
fine, another temporary option would be to switch drivers back and forth
between lp.o (for printing through /dev/lp0) and the hpoj drivers (for
scanning).  Although this requires more effort, at least you're not wasting
an entire CPU.  :-)
