FWIW, another user reported seeing the same problem on a different machine: ``` Radek 2023-03-14 08:00:31 UTC I am experiencing the same issue with kernel >6.2.x on Toshiba Z30 with Alps PS/2 DualPoint trackpoint / touchpad. The cursor jumps top right even with the lowest sensitivity settings. It works just fine with 6.1 or lower. ``` Pali, or anybody else: anyone any idea what's might be wrong there? There afaics is only one recent commit to the alps driver (292a089d78d3 ("treewide: Convert del_timer*() to timer_shutdown*()")); it it maybe worth trying to revert it? Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
