Public bug reported:
Running kernel 5.15.7 (also not working in earlier versions) + Kubuntu 21.10
I have an HP Probook X360 435 g7 with an "ELAN071B:00 04F3:312C Touchpad"
The touchpad usually works fine, but sometimes it stops working either during
reboot or after wake from suspend. I thought the issue might be related to
runtime power-management, but I set power/control to "on" with a udev rule for
my touchpad and the boot error still happens sometimes. I haven't had the
touchpad stop working after wake from suspend since setting the "on" option,
but I can't yet tell for certain whether the udev rule fixed that aspect of the
bug because it occurs so infrequently & at irregular intervals.
Additionally, (not after boot, only after wake from suspend) my touchpad
sometimes gets detected as a mouse, disabling features like scrolling
and disable while typing.
While booting I always get this error (which does not break the touchpad):
ACPI BIOS ERROR (bug): Could not resolve symbol [\_SB.PCI0.BUSB.SAT1],
AE_NOT_FOUND (20210730/dswload2-162)
ACOU Error: AE_NOT_FOUND, During name lookup/catalog (20210730,psobject-220)
That error doesn't seem to be directly causing any issues because everything
still works fine. However, I sometimes get the below error during boot, causing
my touchpad to fail:
hid(null): reading report descriptor failed
i2c_hid_acpi i2c-ELAN071B:00: can't add hid device: -5
I thought the two might be somehow related because they both mention
acpi.
Attached are (in a tarball because of 1 attachment limit) copies of
/proc/acpi and /proc/bus/input/devices, and outputs from dmesg, udevinfo
for the touchpad device, lspci -vvnn, and dmidecode.
