The Linux kernel versions 7.1.1 and 7.0.13 have been released, addressing several performance and stability issues, particularly related to GPU stutter and silent lockups. Key improvements include the removal of an AMDGPU retry loop that caused desktop freezing and updates that ensure memory writes are observed across ARM64 cores. The driver core now also prevents devices from being attached to unregistered buses, stopping hardware from disappearing until a reboot. Additionally, a critical deadlock in TCP urgent data signaling has been resolved, enhancing system responsiveness and security against potential denial of service attacks

Linux kernel 7.1.1 and 7.0.13 release fix GPU stutter and silent lockups

The latest stable kernel drops remove a pointless AMDGPU retry loop that used to freeze desktops for a full second during page fault recovery. ARM64 platforms running Azure or NVIDIA silicon get an automatic workaround for a broadcast TLB bug that left memory writes unobserved across cores. Driver core updates now reject devices attached to unregistered buses, which stops hardware from silently vanishing until the next reboot. A quiet network signaling deadlock gets replaced with RCU locking to prevent remote denial of service vectors and eliminate softirq lockups during urgent TCP traffic.
