I could boot Kubuntu 8.04 with ASUS P5VD2-MX motherboard without any problems. Since I installed 9.04, it cannot boot without adding the boot option "ACPI=off". https://bugs.launchpad.net/ubuntu/+source/linux/+bug/372375 contains collected files with debug information.
The same problem to me. In fact, I have two PCs with this motherboard, both with nVidia video board, one booting without any ACPI problem with kernel 2.6.24.24 and the second with "ACPI=off" with kernel 2.6.28.13 and can not use the nVidia video board with nvidia driver because X server can not access the board (finishes with errors). Nowadays I am using vesa driver instead. I've tried, in the last one, booting with several ACPI options without success (noapic, ht, nolapic, noirq, etc.). I've made this tests with kernels 2.6.28.11, 28.13 and 2.6.30 with the, basically, same bad results. I've filed the bug in the same link that Johan does.
These are the logs with 2.6.28 kernel http://launchpadlibrarian.net/28596603/BootDmesg.txt http://launchpadlibrarian.net/28596605/CurrentDmesg.txt http://launchpadlibrarian.net/28596607/HalComputerInfo.txt The original reporter would provide logs with latest kernel.
Will you please capture the screenshot when the system hangs with ACPI enabled? Please also attach the output of acpidump. Thanks.
The Screenshot of hanging kernel 2.6.30, http://launchpadlibrarian.net/27955524/DSC09842.JPG, shows that this is a SATA error. Johan, please make sure this is the screenshot you got when system hangs. please attach the lspci -x output. BTW, does setting CONFIG_SATA_VIA instead of CONFIG_PATA_VIA help?
plus, http://launchpadlibrarian.net/27955388/ProcInterrupts.txt CPU0 CPU1 14: 14557 0 IO-APIC-edge pata_via 15: 0 0 IO-APIC-edge pata_via 21: 46311 0 IO-APIC-fasteoi sata_via, ehci_hcd:usb1, uhci_hcd:usb4 both pata-via and sata-via are loaded? they can co-exist? what if you just clear CONFIG_PATA_VIA?
Post #4 is not the screen I got. Unfortunately I have no camera at my disposal. But it wil also be difficult to make a screenshot of the error, because I cannot reproduce it anymore. Since filing the bug I have kept my system up-to-date as always, but I also re-installed Kubuntu. So I have asked others in the launchpad bug thread if they could still reproduce the error. As to post #5: kernels 2.6.30 and higher also have both CONFIG_PATA_VIA and CONFIG_SATA_VIA set to "y" and these also worked.
okay. it seems that the bug has already been fixed by the upstream kernel. please re-open it if you can 1. reproduce it in the latest upstream kernel. 2. get the screenshot when system hangs
I will test the Koala some day. I discovered that for the 2.6.28 kernel "acpi=off" is needed only when video drivers (nvidia) are installed. So I have to choose between acpi functions or video drivers. There's no screenshot to take, if I install the video drivers and do not implent "acpi=off", X can not be loaded and the screen turns black for a few seconds (sometimes I see some red or other coloured fragments blinking). I am then dropped to a prompt. After about 10-20 seconds, the screen turns black again (no keyboard input is accepted). This takes a few (3-5) seconds, then I can continue typing. I need to stop kdm to let the screen stop turning black. The errors I saw before seem to stem from the lack of 'noapic' or 'nolapic' boot options.
