Hi, Here is another system with a similar problem: the touchpad randomly stops responding. This is Dell Precision 5470. I saw the issue with the 6.11 kernel series and BIOS 1.24. Now it is updated to
Dell Inc. Precision 5470/02RK6V, BIOS 1.26.0 09/12/2024 and Linux 6.12.1-1.el9.elrepo.x86_64, and the touchpad just broke again. Some "designware" excerpts from dmesg [ 6.415270] input: WACF3233:00 056A:49BB Touchscreen as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-34/i2c-WACF3233:00/0018:056A:49BB.0004/input/input11 [ 6.415443] input: WACF3233:00 056A:49BB as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-34/i2c-WACF3233:00/0018:056A:49BB.0004/input/input12 [ 6.415467] input: WACF3233:00 056A:49BB Stylus as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-34/i2c-WACF3233:00/0018:056A:49BB.0004/input/input13 [ 6.415505] input: WACF3233:00 056A:49BB as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-34/i2c-WACF3233:00/0018:056A:49BB.0004/input/input14 [ 6.415537] input: WACF3233:00 056A:49BB Mouse as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-34/i2c-WACF3233:00/0018:056A:49BB.0004/input/input15 [ 6.415584] hid-generic 0018:056A:49BB.0004: input,hidraw3: I2C HID v1.00 Mouse [WACF3233:00 056A:49BB] on i2c-WACF3233:00 .....

What information would be useful to add? There is a question in the thread above about AGESA version, but I don't see the AGESA string in the dmidecode output on my system.
