Hi Chris, Thanks for reporting this bug.
The faulting memory addresses alone are not sufficient to have an idea of what is going on. Also, they might not necessarily indicate a memory problem, but incorrect code in whatever part of the kernel, targeting a memory address that is incorrectly calculated or no longer valid. Could you please upload the crash dmesg files? They should contain stack traces that provide more context about the faulty memory address. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1898091 Title: Multiple random crashes for the past week Status in linux package in Ubuntu: Confirmed Bug description: For the past week or so, I have started to have random crashes. Somtimes it is just an app that crashes, sometimes the machine freezes up completely and sometimes it just reboots. I ran a memory test for about 8 hours over the weekend and it found no issues. Looking through some of the crash dmesg files I see: 202009290318/dmesg.202009290318:1186:[ 5527.345666] BUG: unable to handle kernel paging request at ffffffffab1bd511 202009291228/dmesg.202009291228:1194:[12423.898689] BUG: unable to handle kernel paging request at ffffffffffffff8e 202009301804/dmesg.202009301804:1386:[31355.601321] BUG: unable to handle kernel paging request at ffffffffb2cbb6cf 202010011046/dmesg.202010011046:1200:[ 3081.774984] BUG: unable to handle kernel paging request at ffffa0bd8f625a50 Which still leads to think a memory issue. Going to run a longer memtest. I am usually pretty good and figuring out what is going on but this time I need some help to make sure I am on the right track or tell me I am completely wrong. Thanks in advance.
