Which new kernel to be specific? Did you try any upstream kernels, like v3.14-rc8? 2.6.32 is obsolete for years as far as upstream is concerned Hi, Please try the lastest upstream kernel (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git) And post the dmesg/acpidump here. Thanks in advance. The patch in comment #3 implements the new "auto-serialize" feature, which should help in these ways: 1) The AE_ALREADY_EXISTS error should go away 2) The \_SB_.PCI0._OSC method should now execute properly, without aborting So, please try the patch. thanks. Thanks to all for your suggestion. Actually this issue was one my customer server , customer replaced motherboard of server and now everything is working fine. According to ACPICA BZ946 (https://bugs.acpica.org/show_bug.cgi?id=946), this seems to be a BIOS bug. It will always be great if you can test the workaround shipped in the latest kernel and post result here. |
