Thanks Guilherme, shame on me for not even checking that :) I will try with 5.4.0-39 and report back. It takes a while for our workload to run before it starts hitting the issue, but I can give a somewhat confident answer in an hour or so. By tomorrow I will be very sure. I'm optimistic. -- You

I'm sad to say, but it seems it did not fix our problem. The crash happened again after running for about an hour: [ 4914.661585] BUG: unable to handle page fault for address: ffb0 [ 4914.661620] #PF: supervisor read access in kernel mode [ 4914.661638] #PF: error_code(0x) -

The test on 5.4.0-40.44 from focal-proposed was successful, so I would say that the fix did it. Thanks for including it! -- 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/1885010 Title:

The long production job with the custom built kernel finished successfully. I'm very confident this fixes our issue. Now running with 5.4.0-40.44 from focal-proposed as a test. I'll let it run for a few hours. It usually hits the crash in an hour or so. -- You received this bug notification

Hi Matthew, thanks a lot for looking into this. Like you, I looked at Git to double-check, and thought the fix was in there, but it was next on my list to actually double-double-check, since I thought it so strange the issue wasn't gone. Thanks for offering to build a test kernel! I will have a

No worries Guilherme, that explains it. I've now built my own kernel from the Ubuntu-5.4.0-38.42 Git tag, which I've verified includes the fix. I'm running our workload again with this kernel and will know within a few hours whether it's looking good. The job as a whole is going to take the full
