Bug 165380 – >=gentoo-sources-2.6.19-r4 - Logitek Mouse generates "extra" events

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Dmitry S. Makovey 2007-02-05 01:16:36 UTC]

I recently updated from 2.6.19-r3 first to r4 then to r5 and my mouse (Logitech Trackman) started to generate extra evens when using scroll wheel. Interestingly enough it only happens on first boot. If I reboot machine (warm reboot) the problem goes away. Apparently there was something in the patches for r4 and r5 that triggered behavior. 

Reproducible: Always

Steps to Reproduce:
1. build gentoo-sources-2.6.19-r4+
2. reboot machine using newly built kernel


Actual Results:  
run 'xev' and use scroller - notice how whenever scroller changes direction (after scrolling up you start to scroll down for example) mouse generates button 2 and 3 pressed event.

Expected Results:  
Should be producing only button 5 and 4 events and no 2 and 3 in between

Motherboard: M2N-SLI Deluxe
Mouse: Logitech TrackMan using PS/2 port (it's on KVM switch "Freedom9")
X11: xorg-7.1 (I'm tracking "stable")

I can provide any additional information if needed.

[Comment 1 Daniel Drake (RETIRED) 2007-02-05 15:05:53 UTC]

Strange, as nothing inbetween -r3 and -r4 should affect anything like this. Can you confirm that rebuilding 2.6.19-r3 using the exact same .config as r4 causes this problem to not appear on a 2.6.19-r3 cold boot (and reconfirm that it DOES then reoccur on a 2.6.19-r5 cold boot)?

If you can, then try reverting this patch from 2.6.19-r4:
http://dev.gentoo.org/~dsd/genpatches/trunk/2.6.19/1001_linux-2.6.19.2.patch

[Comment 2 Dmitry S. Makovey 2007-02-06 04:45:07 UTC]

For now I don't have much time to recompile/reboot, but got bit more info. 

I confirmed one more time that on cold boot 2.6.19-r3 doesn't exhibit stated problem.

I'm using genkernel for compilation so I did a diff on both configs:

# diff kernel-config-x86-2.6.19-gentoo-r3 kernel-config-x86-2.6.19-gentoo-r5
3,4c3,4
< # Linux kernel version: 2.6.19-gentoo-r3
< # Sat Jan 13 03:06:52 2007
---
> # Linux kernel version: 2.6.19-gentoo-r5
> # Wed Jan 31 00:45:51 2007

which for me means - they're identical (configs).

I'll try to recompile -r3 without patch again and post the result.

I'll test patch mentioned here too and see if it helps.

[Comment 3 Dmitry S. Makovey 2007-02-28 00:33:13 UTC]

I just tested got same issue with -r3. So I guess it must either marginal hardware or something about 2.6.19. Feel free to close the bug or mark it as it seem fit. Can't reliably reproduce problem with r3, nevertheless it's possible so I'd say it must me something with hardware/drivers and not gentoo patches.
