KH,
Just make sure I understand details.
Commit "HID: i2c-hid: Don't reset device upon system resume
If you revert this it's fixed on this system?
Yes. Once reset is used instead of the issue is gone.
In that commit you had mentioned if this causes problems it might be worth
quirking just Raydium but commit afbb1169ed5b58cfca017e368b53e019cf285853
confirmed that it helped several other systems too.
If the conclusion from this investigation this is only fixable via
touchpad FW update
it might be worth quirking this touchpad/touchpad FW/system combination.
Hopefully there’s a better solution from ALPS :)
Also Cc Mario because this could relate to BIOS.
Also I assume this is on current stable BIOS/EC release, right?
Yes. The BIOS version is 1.10.1.
The IRQ storm stops as soon as the touchpad gets touched.

Hi Ota-san,
OK, we will look into it.
Hi Kai-Heng,
We will try to reproduce this issue first, could you please tell me the
target Ubuntu version?
It’s distro-agnostic, any distro with mainline Linux can reproduce the
issue.

Best regards,

Subject: Alps touchpad generates IRQ storm after S3
Hi Masaki,
The Alps touchpad (044E:1220) on Dell Precision 7530 causes IRQ storm
after system suspend (S3).
Commit "HID: i2c-hid: Don't reset device upon system resume” which solves
the same issue for other vendors, cause the issue on Alps touchpad.
So I’d like to know the correct command Alps touchpad expects after
system resume.
Also Cc Mario because this could relate to BIOS.
