I belive it should work in this situation.. environment: P4C800 motherboard, P4-2.4 cpu (APIC 2.0 on) Promise 20378 SATA controller on the motherboard (sil_promise driver) Maxtor diamondmax plus 9 200G sata disk (and an empty PCI expander plus some more other under-testing hardware which doesn't matter in the experiment) mainline kernel 2.6.11 serial and VGA console, root on NFS steps to the lockup: 1. booting the machine with sata drive on the promise controller 2. dd if=/dev/sda of=/dev/null bs=4k 3. unplug the power from drive 4. waiting about 2 seconds 5. plug the power back dd stucked in 'D' here for 10-15 seconds and than the kernel say: ata1: command timeout and voila, the box is dead, but without any message from the NMI watchdog :( thanks in advance! dap:# cat /proc/interrupts CPU0 0: 685561 IO-APIC-edge timer 1: 8 IO-APIC-edge i8042 4: 2666 IO-APIC-edge serial 8: 4 IO-APIC-edge rtc 9: 1 IO-APIC-level acpi 12: 93 IO-APIC-edge i8042 14: 12810 IO-APIC-edge ide0 169: 90085 IO-APIC-level eth0, uhci_hcd 177: 4 IO-APIC-level ehci_hcd, libata 185: 7 IO-APIC-level ide2 193: 0 IO-APIC-level uhci_hcd, uhci_hcd 201: 103 IO-APIC-level uhci_hcd 209: 0 IO-APIC-level Intel ICH5 NMI: 686357 LOC: 685462 ERR: 0 MIS: 0 dap:# lspci 0000:00:00.0 Host bridge: Intel Corp. 82875P Memory Controller Hub (rev 02) 0000:00:01.0 PCI bridge: Intel Corp. 82875P Processor to AGP Controller (rev 02) 0000:00:03.0 PCI bridge: Intel Corp. 82875P Processor to PCI to CSA Bridge (rev 02) 0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (rev 02) 0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (rev 02) 0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02) 0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (rev 02) 0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02) 0000:00:1e.0 PCI bridge: Intel Corp. 82801 PCI Bridge (rev c2) 0000:00:1f.0 ISA bridge: Intel Corp. 82801EB/ER (ICH5/ICH5R) LPC Bridge (rev 02) 0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02) 0000:00:1f.3 SMBus: Intel Corp. 82801EB/ER (ICH5/ICH5R) SMBus Controller (rev 02) 0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) 0000:01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev a1) 0000:02:01.0 Ethernet controller: Intel Corp. 82547EI Gigabit Ethernet Controller (LOM) 0000:03:04.0 RAID bus controller: Promise Technology, Inc.
