I've just cvsup'ed to RELENG_4 and seeing "hangs" while heavy disk IO is performed (like bonnie test). Kernel says: /kernel: ahc1: Timedout SCB already complete. Interrupts may not be functioning. This is definitly NOT a hardware problem because when I replace all hardware (yes even different scsi, sym instead ahc) problem still the same. There isn't any problem when kernel is compiled as non-SMP. Does anyone seen something like this problem? dmesg.boot: ====================================================================== Jul 18 23:19:18 mh /kernel: Copyright (c) 1992-2001 The FreeBSD Project.
