5 is QH_STATE_COMPLETING. That explains why the BUG() fires. At this point it's beyond me.

Those messages are from the card reader. It doesn't seem to be working right. It returns the "end-of-data" error in response to a PREVENT MEDIUM REMOVAL command and it returns a phase error in response to a READ command. In spite of the fact that it claims to have a 256 MB card present. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
