Hi,
for some unfathomable to me reason, the commit in $Subject breaks booting of the 32-bit partition of one of my test boxes. The box doesn't finish booting (normally it boots in text mode, there is no X server setup on it) but it is still responsible in the sense that I can reboot it with the Sysrq combination. No other keystrokes have effect.
I bisected it to this patch and confirmed that it really is the culprit by reverting it ontop of latest Linus tree. With it reverted, it boots fine.
.config is attached, lemme know if you need more info to debug this.
Thx.
