From: Damjan Jovanovic on 13 Apr 2010 07:30 This fixes a regression introduced in Linux 2.6.2 where mice that sporadically produce bad parity go crazy and start jumping around and clicking randomly, which never happens in any version of Windows running on the same hardware. The bugzilla bug is https://bugzilla.kernel.org/show_bug.cgi?id=6105 The patch works by always accumulating a full PS/2 packet, then ignoring the packet if any byte had a bad checksum. A month of testing it against an affected mouse has revealed it works perfectly in practice. This is the third resend, also CC'ed to lkml and Andrew Morton this time, because the previous 2 emails to linux-input(a)vger.kernel.org and the input/mouse maintainers from 28 March 2010 were ignored.
