Subject: Bugzilla # 16395: Regression in 2.6.35-rc4 since commit 0b28bac5aef7bd1ab213723df031e61db9ff151a on HP Mini 110 Netbook
Date: Wed, 14 Jul 2010 18:58:39 -0500 [thread overview]
Message-ID: <4C3E4F2F.3090404@lwfinger.net> (raw)
Since the commit in the title, a kernel built on an HP Mini 110 Netbook no
longer has keyboard input. The main difference is that CONFIG_SERIO_I8042 is no
longer defined. When this equal yes, the keyboard works. The faulty commit was
located by bisection and has been verified by reverting the patch.
Further investigation shows that the faulty hunk is

i8042 is the chip over which the standard AT keyboard and PS/2
mouse are connected to the computer. If you use these devices,
Reverting this one hunk alone results in a working system. Obviously, this
Netbook does not have X86_MRST set.
