In the past few days of use, I've still had an occasional missed keypress, down to maybe one keypress every two or three entries of the (long) passphrase. Plymouth and cryptsetup are being run from the initramfs, since this is full disk encryption.
I have tested the keyboard itself after booting by firing up Leafpad and looking for missed presses, finding none. Still, I cannot rule out a keyboard driver bug that early in the boot process, so plymouth may or many not even be at fault for those. Still, it's been a hell of a lot easier to boot the MSI since the last round of plymouth fixes-thanks! > Date: Fri, 19 Mar 2010 02:49:50 +0000 > From: sc...@canonical.com > To: lukek...@hotmail.com > Subject: RE: [Bug 537793] Re: missed passphrase keypress bug is back on MSI > Wind U100 > > On Fri, 2010-03-19 at 00:50 +0000, Luke wrote: > > > A quick test boot (I'm in a park on batteries) showed no sign of the > > keypress bug with the new plymouth, smoothly took every character.
