Hello Hans,

Thanks for your response as well, and my apologies for the delay, I wanted to
do a bit of further testing.

It hadn't specifically occurred to me that rebooting from Windows might be
causing an issue.  I'm aware that Windows by default does save some state data
for a faster boot, but I didn't think any of this would make any difference in
a normal reboot once you hit GRUB and select your Linux installation.

Regardless, it does seem like making sure to do a cold boot every time has
resulted in the accelerometer working a bit more reliably.  However, before, I
was even rebooting from Fedora back into Fedora and still having trouble with
it, so I don't think it's specifically Windows causing the symptoms either. 
Not sure what to make of it yet...

In any case here are your requested details:

The path you specified did exist:
i2c-MXC6655:00 ->
../../../devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-MXC6655:00

# cat /sys/bus/i2c/devices/i2c-MXC6655\:00/firmware_node/path 
\_SB_.PCI0.I2C0.ACC0

I'm attaching the dmesg and acpidump.  These are from a persistent Fedora
install which was updated to 6.7.7-200.fc39.x86_64.

Thanks!
Kirk
