This error message can be reached\nseveral millions of times per second, causing spam to the kernel's printk\nbuffer and bringing the CPU usage up to 100% (so, it should be rate\nlimited). However, since there is at least one driver that is in the\nmainline and suffers from the error condition, it is more useful to\nerr_printk() here instead of just rate limiting the error message (in hopes\nthat it will make it easier for other drivers that suffer from this issue\nto be spotted).\n\ud83d\udccf Published: 2024-05-21T15:03:38.436Z\n\ud83d\udccf Modified: 2025-05-15T12:32:29.426Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/de4afec2d2946c92c62a15ab341c70b287289e6a\n2. https://git.kernel.org/stable/c/510e1a724ab1bf38150be2c1acabb303f98d0047", "creation_timestamp": "2025-05-15T13:33:46.000000Z"} 2025-05-15T13:33:46+00:00
