[Kernel-packages] [Bug 1765232] Re: Kernel 4.15.0-15 breaks Dell PowerEdge 12th Gen servers
I just did a fresh install of the April 24 daily build with kernel 4.15.0-19 on my Dell R820 and I can confirm this has been fix.

Can you also give the mainline kernel a try: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17-rc1/ If the mainline kernel does not have the bug, please test the latest upstream 4.15 kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.18/ -- 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/1765232 Title: Kernel 4.15.0-15 breaks Dell PowerEdge 12th Gen servers Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Bug description: For Ubuntu 18.04 amd64 server, I updated the kernel from 4.15.0-13 to 4.15.0-15.

If the bug still exists in proposed, we can perform a kernel bisect to identify the commit that introduced this regression. Also, if this bug still exists in proposed, it might be good to see if this bug also exists in the latest mainline kernel, which can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17-rc1/ -- 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/1765232 Title: Kernel 4.15.0-15 breaks Dell PowerEdge 12th Gen servers Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Bug description: For Ubuntu 18.04 amd64 server, I updated the kernel from 4.15.0-13 to 4.15.0-15.
