SHI XUDONG, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product-support/product/optiplex-990/drivers an update to your computer's buggy and outdated BIOS is available (A18). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Attachment removed: "AlsaInfo.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285511/+files/AlsaInfo.txt ** Attachment removed: "BootDmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285512/+files/BootDmesg.txt ** Attachment removed: "CRDA.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285513/+files/CRDA.txt ** Attachment removed: "CurrentDmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285514/+files/CurrentDmesg.txt ** Attachment removed: "Lspci.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285515/+files/Lspci.txt ** Attachment removed: "Lsusb.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285517/+files/Lsusb.txt ** Attachment removed: "ProcCpuinfo.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285518/+files/ProcCpuinfo.txt ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285519/+files/ProcEnviron.txt ** Attachment removed: "ProcInterrupts.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285520/+files/ProcInterrupts.txt ** Attachment removed: "ProcModules.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285521/+files/ProcModules.txt ** Attachment removed: "PulseList.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285522/+files/PulseList.txt ** Attachment removed: "UdevDb.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285523/+files/UdevDb.txt ** Attachment removed: "UdevLog.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285524/+files/UdevLog.txt ** Attachment removed: "WifiSyslog.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404766/+attachment/4285525/+files/WifiSyslog.txt ** Description changed: ProblemType: KernelOops Annotation: Your system might become unstable now and might need to be restarted.
