** Description changed: ubuntu 10.04 with a kernel 2.6 or lower works well on my SIS motherboard, but using ubuntu 10.10 or higher I cannot boot into Ubuntu. I'm now using ubuntu 12.04 on an ASUS F81SE notebook with SIS motherboard,and I can't boot it normally. - Ubuntu kernel version bisect revealed: + Mainline kernel version bisect revealed: v2.6.34-rc1/:well v2.6.34.1-maverick/:fail WORKAROUND: Add: acpi=off to the grub line. WORKAROUND: Disable wlan in bios. WORKAROUND: Download kernel 2.6.34 or lower (used by ubuntu 10.04) from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and boot the system by this kernel. So i guess ubuntu must have removed sis motherboard acpi support from kernel 2.6 or higher(perhaps linux kernel team should be responsible for it).Please give me an a explanation about it . Something has to be pointed out that this bug has nothing to do with the video card or video driver! This bug exists in ALL computers based on SIS motherboard running ubuntu 10.10 or above. --- AcpiTables: AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
