It certainly worked when I originally implemented it. If it didn't work
that way before 2.6.19-rc1 butchered it then that would have been a bug
that should have been fixed.
Oh. OK.
Meanwhile, 2.6.19-rc6 remains unfixed.
Has anyone verified that nmi watchdog works at all in 2.6.19-rc6? I
haven't built a kernel since rc2, other things have been taking my time.

Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a
normal user and is setuid root, with the "vi" line edit mode selected,
and the character set is "big5," an off-by-one errors occurs during
wildcard (glob) expansion.
