The recent posting on the subject of message-sending deadlocks prompted me to take a second look at my serial TTY driver. 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!
