Description Eric F. GARIOUD 2010-09-14 08:58:54 UTC
- After booting, the very first character hit on the keyboard (on the login prompt) is systematically ignored (not echoed as well) consecutive ones are taken into account.
- Does not seem to occur for the password field
- After a successfull login, at the shell prompt, the very first character is systematically ignored. consecutive ones are ignored or not more on a random basis. (Could be linked with the time between two characters)
- These observations are also valid for alt+Fx hits.


Reproducible: Always




1- This problem does not occur on the same system with the same hardware and identical /usr/src/linux/.config with 2.6.34-r1
2 - This problem does not occur on the same system with the same hardware but different /usr/src/linux.config with all stable versions since 2.6.29-r6
3 - Keyboard is a Logitech UltraX Premium (USB HID compliant)

Will provide any additional information requested.

Can you please test it with a different USB HID keyboard?
Comment 2 Mike Pagano gentoo-dev 2010-09-18 17:01:51 UTC
From the 2.6.34.7 release email:

"...It fixes a single bug that a number of users have reported in that their
USB devices no longer work properly.  Sometimes it causes lost
keystrokes,.."

Can you please test with gentoo-sources-2.6.34-r10 and let us know the outcome.

Thanks & apologizes to Robin Johnson : I had not managed to find anything looking like a keyboard apart from a 25 years old Lexmark and a Bösendorfer 170... Definitely not USB HID...

Thanks & apologizes to Mike pagano : Despite careful readings of changelogs, I had not read that important piece of information you mention.

I am happy to confirm that I cannot reproduce this bug under gentoo-sources 2.6.34-r10
