This change is in the recv_isr routine and in the shuffling and reshuffling I'm not sure which amended version actually went out. The faulty (my opinion) version turns interrupts on in recv_isr. This should not be done here and will indeed cause crashes which occur at irregular times (I believe only when an interrupt occurs before recv_isr actually completes.) Hope this helps. - jg - P.S. BTW the slip driver released is badly broken. I have sent an updated, and not so broken version to Russ. You might ask him for it if you've any interest, or get back to me and I'll get it to you ... sometime!
