@Marks,
Could you help test a new kernel, the kernel applied the patch below as
requested by community, and help collect dmesg with "dyndbg="file
drivers/pci/* +p", thanks.

@Marks,
This is the testing kernel with the patch below applied:
https://people.canonical.com/~hwang4/lp2111521/test12/
Please add "dyndbg="file drivers/pci/* +p" and collect a dmesg.txt,
thanks.
BTW, I was OOO the past week, so it is a bit late to respond.

I applied the patch to ubuntu 6.8 kernel, this is the testing kernel:

Could you help test if the kernel fixed the existing issue and it didn't
introduce regression?
thx.

The 6.11 kernel will get the stable paches from 6.12 longterm tree, so
6.11 will include the fix automatically.
Since you are the author of the fix, if you could backport the fix to 6.6
longterm tree, the ubuntu-6.8 kernel will include the fix automatically as well.

Could you help test https://kernel.ubuntu.com/mainline/v6.12/ and

The drivers for this device are spi/spi-pxa2xx*, mfd/intel-lpss* and
input/keyboard/applespi*, I compared 6.11 and 6.12, there is no
significant change (nearly no change at all).
This is the commits diff between test1 and test2, the commits below only
exist in test2, so some of them caused this bug:
pick 11bd03202d6a ALSA: ump: Use guard() for locking
