Is anybody knows the steps to reproduce this issue? We are also facing the same below TB in our testbed and we are planning to take the patch mentioned in comment #15. Even though we are using this kernel from long time and seen this issue on very few nodes. Appreciate your help in this regard.

Thank you, Andrea. We're trying to repro it, but it's not so far. Can you create a proposed kernel, which includes this fix? Once we can reproduce it, will let you know asap. But we can prepare the proposal kernel in the meantime. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.4 in Ubuntu. https://bugs.launchpad.net/bugs/1981658 Title: BUG: kernel NULL pointer dereference, address: 0008 Status in linux package in Ubuntu: Confirmed Status in linux-hwe-5.4 package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Status in linux-hwe-5.4 source package in Bionic: Confirmed Bug description: Hi, On one of the main US Ubuntu Archive servers (banjo), we decided to reboot into a HWE kernel.

@squirrelsc the next Azure kernel in Focal that will have this fix is going to be 5.4.0-1087.92, but I don't see it in proposed yet. If it helps I can upload to a ppa an "unofficial" Azure kernel with the fix. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.4 in Ubuntu. https://bugs.launchpad.net/bugs/1981658 Title: BUG: kernel NULL pointer dereference, address: 0008 Status in linux package in Ubuntu: Confirmed Status in linux-hwe-5.4 package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Status in linux-hwe-5.4 source package in Bionic: Confirmed Bug description: Hi, On one of the main US Ubuntu Archive servers (banjo), we decided to reboot into a HWE kernel.

I think this might be fixed by `55573f3a3f352 tcp: make sure treq->af_specific is initialized` that is currently applied to 5.4.0-123.139 in focal-proposed. It'd be great if someone that is able to reproduce the problem could try to install this new kernel from -proposed and verify if it's still happening. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.4 in Ubuntu. https://bugs.launchpad.net/bugs/1981658 Title: BUG: kernel NULL pointer dereference, address: 0008 Status in linux package in Ubuntu: Confirmed Status in linux-hwe-5.4 package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Status in linux-hwe-5.4 source package in Bionic: Confirmed Bug description: Hi, On one of the main US Ubuntu Archive servers (banjo), we decided to reboot into a HWE kernel.
