[Kernel-packages] [Bug 1874221] Re: Fix potential null pointer dereference on kernfs
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: verification-needed-eoan -- 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/1874221 Title: Fix potential null pointer dereference on kernfs Status in HWE Next: New Status in linux package in Ubuntu: Incomplete Status in linux source package in Eoan: Fix Committed Bug description: [Impact] We are seeing a null kernel dereference on kernfs during system sleep stress.
