Sure enough, that's what was causing my system hangs. Apparently, the RESUME message to the filesystem (sent out of interrupt service when we get enough characters to satisfy a read request) was occasionally colliding with a READ, WRITE, or IOCTL message being sent from the filesystem to the TTY driver. Now, I have to figure out a workaround... +----------------+ Jim Paradis linus--+ +--+-------------+ | Encore Computer Corp. necntc--| | | E N C O R E | | 257 Cedar Hill St. ihnp4--+-encore!paradis | +-------------+--+ Marlboro MA 01752 decvax--| +----------------+ (617) 460-0500 talcott--+ ...coated with sesame seeds, and garnished with lark's vomit!
