[Same experience here, with a guess at what is causing this. My system is an IBM ThinkPad X20. Note I am not really a kernel hacker, and the move in CURRENT to threads has really dated my knowledge.] -- Moving from FreeBSD 5.1beta2 to a slightly post-release CURRENT signals have stopped working under bash and sh for ordinary users (but not for root). Creating a user from scratch verified that the problem did not stem from initialization process problems. The following patch to trap.c might have a failure in the logic by replacing the call via PCPU_GET(spinlocks) by the direct reference to the thread->critnest, but this is just a guess. *** /usr/src-5.1-BETA2/sys/i386/i386/trap.c Wed Apr 30 19:59:27 2003 --- /usr/src-QUIP/sys/i386/i386/trap.c Sat Jun 7 09:34:34 2003 *************** *** 222,231 **** type); /* * Page faults need interrupts diasabled until later, ! * and we shouldn't enable interrupts while holding a ! * spin lock. */ ! if (type != T_PAGEFLT && PCPU_GET(spinlocks) == NULL) enable_intr(); } } --- 224,233 ---- type); /* * Page faults need interrupts diasabled until later, ! * and we shouldn't enable interrupts while in a ! * critical section. */ ! if (type != T_PAGEFLT && td->td_critnest == 0) enable_intr(); } } -- Mark Evenson <[EMAIL PROTECTED]> "A screaming comes across the sky.
