Subject    : bug in `tty: BKL pushdown'?
Submitter  : Johannes Weiner <hannes@saeurebad.de>
Date       : 2008-05-18 2:16

This entry is being used for tracking a regression from 2.6.25.  Please don't
close it until the problem is fixed in the mainline.
Comment 1 Alan 2008-06-02 01:29:49 UTC
Appears to be a bug in the user space apps.
Comment 2 Alan 2008-06-09 02:34:12 UTC
ignore that comment I attached  comment 1 to the wrong bug
Comment 3 Alan 2008-06-09 08:24:28 UTC
Can't duplicate this behaviour
Comment 4 Johannes Weiner 2008-06-09 10:11:20 UTC
I have screen running in LANG=en_US.utf8 and LC_COLLATE=C and screen windows and display in utf8 mode (utf8 on on), I forgot to mention.  Perhaps this makes any difference.
Comment 5 Alan 2008-06-10 02:39:01 UTC
None at all. Works perfectly for me.
Comment 6 Johannes Weiner 2008-06-10 03:16:45 UTC
If this patch only changes the way the code is locked (without intented effects to  userspace) how could this possibly happen?  Maybe an unreliable bisection result?  I will rerun the bisection session, perhaps I overlooked something.
Comment 7 Johannes Weiner 2008-06-10 03:36:03 UTC
Alan, you need at least a caption (or hardstatus)

# .screenrc:
caption always "%-Lw %n%f* %t +%Lw"

for example. If neither are enabled, no breakage.
Comment 8 Alan 2008-06-10 03:41:11 UTC
still doesn't break for me... 8(
Comment 9 Rafael J. Wysocki 2008-06-16 06:11:42 UTC
Problem has been confirmed to be present in 2.6.26-rc6-git2.
