Gladly. I wasn't sure which kernel you would like me to use, so I chose a sample of 3: 1. linux-2.6.25 (from git) just before the commit causing the lockups 2. linux-2.6.26 (with "hpet=disabled") 3. Debian stock 2.6.26 ("linux-image-2.6.26-1-amd64", also with HPET disabled) Using 2.6.25 at the commit before the one that caused lockups: $ cat /proc/iomem 00000000-0009f3ff : System RAM 0009f400-0009ffff : reserved 000f0000-000fffff : reserved 00100000-77fdffff : System RAM 00200000-0056ca21 : Kernel code 0056ca22-006ce3d7 : Kernel data 00753000-0079a3c7 : Kernel bss 77fe0000-77fe2fff : ACPI Non-volatile Storage 77fe3000-77feffff : ACPI Tables 77ff0000-77ffffff : reserved 78000000-7fffffff : pnp 00:0d d8000000-dfffffff : PCI Bus #01 d8000000-dfffffff : 0000:01:05.0 d8000000-d8ffffff : uvesafb e0000000-efffffff : PCI MMCONFIG 0 e0000000-efffffff : reserved fdc00000-fdcfffff : PCI Bus #02 fdcff000-fdcff0ff : 0000:02:05.0 fdcff000-fdcff0ff : r8169 fdd00000-fdefffff : PCI Bus #01 fdd00000-fddfffff : 0000:01:05.0 fdee0000-fdeeffff : 0000:01:05.0 fdefc000-fdefffff : 0000:01:05.2 fdefc000-fdefffff : ICH HD audio fdf00000-fdffffff : PCI Bus #02 fe020000-fe023fff : 0000:00:14.2 fe020000-fe023fff : ICH HD audio fe029000-fe0290ff : 0000:00:13.5 fe029000-fe0290ff : ehci_hcd fe02a000-fe02afff : 0000:00:13.4 fe02a000-fe02afff : ohci_hcd fe02b000-fe02bfff : 0000:00:13.3 fe02b000-fe02bfff : ohci_hcd fe02c000-fe02cfff : 0000:00:13.2 fe02c000-fe02cfff : ohci_hcd fe02d000-fe02dfff : 0000:00:13.1 fe02d000-fe02dfff : ohci_hcd fe02e000-fe02efff : 0000:00:13.0 fe02e000-fe02efff : ohci_hcd fe02f000-fe02f3ff : 0000:00:12.0 fe02f000-fe02f3ff : ahci fec00000-fec00fff : IOAPIC 0 fec00000-fec00fff : pnp 00:0d fed00000-fed003ff : HPET 0 fed00000-fed003ff : 0000:00:14.0 fee00000-fee00fff : Local APIC fff80000-fffeffff : pnp 00:0d ffff0000-ffffffff : pnp 00:0d Using 2.6.26 (custom compiled) with "hpet=disabled" 00000000-0009f3ff : System RAM 0009f400-0009ffff : reserved 000f0000-000fffff : reserved 00100000-77fdffff : System RAM 00200000-0057358d : Kernel code 0057358e-006d8e9f : Kernel data 0076e000-007b7447 : Kernel bss 77fe0000-77fe2fff : ACPI Non-volatile Storage 77fe3000-77feffff : ACPI Tables 77ff0000-77ffffff : reserved 78000000-7fffffff : pnp 00:0d 80000000-800003ff : 0000:00:14.0 d8000000-dfffffff : PCI Bus 0000:01 d8000000-dfffffff : 0000:01:05.0 d8000000-d8ffffff : uvesafb e0000000-efffffff : PCI MMCONFIG 0 e0000000-efffffff : reserved fdc00000-fdcfffff : PCI Bus 0000:02 fdcff000-fdcff0ff : 0000:02:05.0 fdcff000-fdcff0ff : r8169 fdd00000-fdefffff : PCI Bus 0000:01 fdd00000-fddfffff : 0000:01:05.0 fdee0000-fdeeffff : 0000:01:05.0 fdefc000-fdefffff : 0000:01:05.2 fdefc000-fdefffff : ICH HD audio fdf00000-fdffffff : PCI Bus 0000:02 fdf00000-fdf1ffff : 0000:02:05.0 fe020000-fe023fff : 0000:00:14.2 fe020000-fe023fff : ICH HD audio fe029000-fe0290ff : 0000:00:13.5 fe029000-fe0290ff : ehci_hcd fe02a000-fe02afff : 0000:00:13.4 fe02a000-fe02afff : ohci_hcd fe02b000-fe02bfff : 0000:00:13.3 fe02b000-fe02bfff : ohci_hcd fe02c000-fe02cfff : 0000:00:13.2 fe02c000-fe02cfff : ohci_hcd fe02d000-fe02dfff : 0000:00:13.1 fe02d000-fe02dfff : ohci_hcd fe02e000-fe02efff : 0000:00:13.0 fe02e000-fe02efff : ohci_hcd fe02f000-fe02f3ff : 0000:00:12.0 fe02f000-fe02f3ff : ahci fec00000-ffffffff : reserved fec00000-fec00fff : IOAPIC 0 fed00000-fed003ff : HPET 0 fee00000-fee00fff : Local APIC Using Debian stock kernel 00000000-0009f3ff : System RAM 0009f400-0009ffff : reserved 000f0000-000fffff : reserved 00100000-77fdffff : System RAM 00200000-0042c443 : Kernel code 0042c444-0053a677 : Kernel data 005de000-00673317 : Kernel bss 77fe0000-77fe2fff : ACPI Non-volatile Storage 77fe3000-77feffff : ACPI Tables 77ff0000-77ffffff : reserved 78000000-7fffffff : pnp 00:0d 80000000-800003ff : 0000:00:14.0 d8000000-dfffffff : PCI Bus 0000:01 d8000000-dfffffff : 0000:01:05.0 e0000000-efffffff : PCI MMCONFIG 0 e0000000-efffffff : reserved fdc00000-fdcfffff : PCI Bus 0000:02 fdcff000-fdcff0ff : 0000:02:05.0 fdcff000-fdcff0ff : r8169 fdd00000-fdefffff : PCI Bus 0000:01 fdd00000-fddfffff : 0000:01:05.0 fdee0000-fdeeffff : 0000:01:05.0 fdefc000-fdefffff : 0000:01:05.2 fdefc000-fdefffff : ICH HD audio fdf00000-fdffffff : PCI Bus 0000:02 fdf00000-fdf1ffff : 0000:02:05.0 fe020000-fe023fff : 0000:00:14.2 fe020000-fe023fff : ICH HD audio fe029000-fe0290ff : 0000:00:13.5 fe029000-fe0290ff : ehci_hcd fe02a000-fe02afff : 0000:00:13.4 fe02a000-fe02afff : ohci_hcd fe02b000-fe02bfff : 0000:00:13.3 fe02b000-fe02bfff : ohci_hcd fe02c000-fe02cfff : 0000:00:13.2 fe02c000-fe02cfff : ohci_hcd fe02d000-fe02dfff : 0000:00:13.1 fe02d000-fe02dfff : ohci_hcd fe02e000-fe02efff : 0000:00:13.0 fe02e000-fe02efff : ohci_hcd fe02f000-fe02f3ff : 0000:00:12.0 fe02f000-fe02f3ff : ahci fec00000-ffffffff : reserved fec00000-fec00fff : IOAPIC 0 fed00000-fed003ff : HPET 0 fee00000-fee00fff : Local APIC Please let me know anything else I can provide, and which kernels you would like me to run to provide it.
