Hello Zhanglei, thanks for confirming the working/broken versions. I am not sure if I will be able to reproduce the issue myself. There are 270 changes between -99 and -100. If you can help me bisect them, we should be able to quickly identify the problem. Would you be able to test the kernels I provide so we can identify the breaking commit? We might need to test up to 9 more kernels.
I have built the first test kernel. It can be found at: https://kernel.ubuntu.com/~kmously/kernel-kmously-d60b65f-bspU/ If you can, please install the linux-image, linux-modules and linux- modules-extra packages from the above link and attempt to reproduce the problem. Thank you. -- 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/1971576 Title: SATA device hot plug regression on AMD EPYC (Asus) server Status in linux package in Ubuntu: Confirmed Bug description: SATA disk hot plug can't work on Ubuntu 20.04 ga-kernel of "Linux version 5.4.0-109-generic", but it works on earlier version of " Linux version 5.4.0-42-generic" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971576/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
