[Test case] 1. Install Ubuntu 2. Check touchpad works or not 3. Install the fixed kmod package 4. Confirm touchpad works [Regression Potential] i2c-i801 was blacklisted due to bug 16602. The user complains an HP Compaq nc6000 notebook cannot suspend without blacklisting i2c-i801. While this is a way to workaround the suspend issue, the proper fix should be in linux kernel. Since nc6000 was a machine sold in 2004, it is too difficult to find someone to verify if it will regress due to this SRU. The rationale to blacklist it is: https://bugs.launchpad.net/ubuntu/+source/hotplug/+bug/16602/comments/5, however it is no longer valid nowadays on modern computers. Besides, there look like to be a quirk in linux kernel that fixes it: https://github.com/torvalds/linux/blame/master/drivers/pci/quirks.c#L1434 [Other Info] rationale of i2c_i801 driver blacklist: https://answers.launchpad.net/ubuntu/+source/kmod/+question/269329 ----------------------------------------------------------------------------------------------- Original bug report: We have a Lenovo Thinkpad machine that requires i2c-i801 kernel module to work, but it is listed in /etc/modprobe/blacklist.conf in Ubuntu. To use the touchpad, users have to remove the i2c-i801 line manually. i2c-i801 in blacklist.conf is a very old workaround to fix HP compaq nc6000 (Bug #16602), this module should be removed from blacklist. There is also another bug (Bug #1475945) that needs this module for Acer trackpad to work.
