I have the same problem like Mark Lanett posted before, but mybe i have some additional information for you...
First: I have the D945GCLF2 Intel Board, riding Atom 330 dual Core CPU on it, chipset is the old Intel 945 (like D945GCLF Board) I had no problems running the plain mainboard (without PCI-Cards plugged in) on Hardy and also on Intrepid (actual kernel on both). I can reproduce soft lockups of the CPUs on hardy AND Intrepid as well, if i follow these steps: 1: Plugin Soundcard in PCI-Slot (soundblaster xifi or terratec Aureon 5.1 PCI make no diff.) 2: Turn on PC 3: everything works fine, on genome systemmonitor are 4 Cores displayed, running fine, soundcard ( terratec) works out of the box 4: shutdown and start or restart 5: System stuckes on booting... every time 6: Unplug Soundcard 7:System starts fine again... after step 7 you can start from step 1 again... everytime the same... maybe something with recognition of new devices from bios? i have tested one thing until now.... after not booting up again, i set in grub acpi=no, now ubuntu starts up, but takes MUCH longer, and after looking into system-monitor in gnome, there is only 1 core displayed.... is there any information i can give to you? sorry for my poor english :) -- BUG: soft lockup - CPU #1 stuck for 11s -- Ubuntu 8.04.1 Kernel 2.6.24-19 https://bugs.launchpad.net/bugs/254326 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
