The git-sched patch in 2.6.23-mm1 freezes my ia64 SN Altix hard on boot.
Not good (tm).
Something broke between the git-sched patch of Sept 26 in 2.6.23-rc8-mm2
and the git-sched patch of Oct 10 in 2.6.23-mm1 on my ia64 SN Altix
system using sn2_defconfig.
I can boot 2.6.23-rc8-mm2 fine, but I freeze early in boot
on 2.6.23-mm1, after the following prints on the console:

The next output that I -would- have expected, based on successful boots
without this patch, but never get, is:

My .config has the following elements matching "SCHED"
# CONFIG_FAIR_GROUP_SCHED is not set
CONFIG_IOSCHED_NOOP=y
CONFIG_IOSCHED_AS=y
CONFIG_IOSCHED_DEADLINE=y
CONFIG_IOSCHED_CFQ=y
CONFIG_DEFAULT_IOSCHED="anticipatory"
CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER=y
CONFIG_SCHED_SMT=y
# CONFIG_NET_SCHED is not set
# CONFIG_USB_EHCI_TT_NEWSCHED is not set
CONFIG_SCHED_DEBUG=y
# CONFIG_SCHEDSTATS is not set
I'm pretty certain that I also saw this hang with the config setting:
CONFIG_FAIR_GROUP_SCHED=y
though there is a small chance I'm confused on that point.
You'll probably need more information, but I can't guess what,
so ask away.
