Subject: Alps touchpad generates IRQ storm after S3
Date: Wed, 28 Aug 2019 14:22:18 +0800 [thread overview]
Message-ID: <44F93018-5F13-4932-A5AC-9D288CDF68DD@canonical.com> (raw)
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.
