I've done a new bisection for this issue (with cold boots instead of reboots) and now end up in the following merge: commit 94468080220162f74dc6ce5c3e95e5fec8022902 Merge: fb7b096 137ee2f Author: Linus Torvalds Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6 Unfortunately I cannot bisect into that merge as I get a NULL pointer bug after typing the passphrase for my encrypted partition. I suspect one of the following commits from that merge: * commit 638b9648ab51c9c549ff5735d3de519ef6199df3 Author: Alan Cox tty: Fix the ldisc hangup race * commit 4165fe4ef7305609a96c7f248cefb9c414d0ede5 Author: Alan Cox tty: Fix up char drivers request_room usage * commit d9661adfb8e53a7647360140af3b92284cbe52d4 Author: Alan Cox tty: Keep the default buffering to sub-page units * commit eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f Author: Ari Entlich tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP The last one is probably the most likely as the issue occurs after an init script loops over all VTs to run 'consolechars' and/or 'charset'. See http://lkml.org/lkml/2010/4/17/48 for my original mail with some additional details.
