Hi I was wondering if anyone has experienced this. Turned our printer on and the machine locked up. It still printed, but it was totally unresponsive even after the printer was turned off again. There were tons of these in /var/log/messages after it was rebooted: Nov 14 09:13:23 brane kernel: lpt0: [GIANT-LOCKED] Nov 14 09:13:23 brane kernel: lpt0: [ITHREAD] Nov 14 09:13:23 brane kernel: lpt0: [GIANT-LOCKED] Nov 14 09:13:23 brane kernel: lpt0: [ITHREAD] Nov 14 09:13:23 brane kernel: lpt0: [GIANT-LOCKED] Nov 14 09:13:23 brane kernel: lpt0: [ITHREAD] Nov 14 09:13:23 brane kernel: lpt0: [GIANT-LOCKED] Nov 14 09:13:23 brane kernel: lpt0: [ITHREAD] Nov 14 09:13:23 brane kernel: lpt0: [GIANT-LOCKED] Nov 14 09:13:23 brane kernel: lpt0: [ITHREAD] +620 more The kernel detects lpt0 as follows: ppc0: <Parallel port> port 0x378-0x37f,0x778-0x77b irq 7 drq 3 on acpi0 ppc0: SMC-like chipset (ECP/EPP/PS2/NIBBLE) in COMPATIBLE mode ppc0: FIFO with 16/16/9 bytes threshold ppbus0: <Parallel port bus> on ppc0 plip0: <PLIP network interface> on ppbus0 lpt0: <Printer> on ppbus0 lpt0: Interrupt-driven port ppi0: <Parallel I/O> on ppbus0 ppc0: [GIANT-LOCKED] ppc0: [ITHREAD] Ian -- Ian Freislich
