The new version of the Linux 7.2 system fixes a bug that reduced the speed of PCIe devices to 2.5 GT/s. This issue occurred when connecting or disconnecting components such as graphics or storage cards, leaving them slower than normal. The update will also be applied to previous versions.
Technical details of the kernel fix 🛠️
The bug originated in PCIe link management, where the system did not correctly renegotiate speed after a hot-plug or hot-unplug event. This left devices stuck in the slow 2.5 GT/s mode instead of reaching their maximum speed. The fix restores dynamic negotiation, allowing the bus to recover full bandwidth without user intervention.
Slowness goes on vacation, and it's not coming back 🚀
Finally, your graphics card will stop acting like a snail with a hangover. It turns out the bug had been hiding for years, waiting for the perfect moment to ruin your gaming session or file transfer. Now, with the update, your devices regain speed without you having to do anything. It almost seems like magic, but it's just code working as it should.
