Hi,
I ran into a "stucked process" when trying to bring down all my CPUs on
a 2.6.30 kernel (+ lttng patchset). It's Intel Core2 Xeon.
My printk output showed :
[ 133.866683] CPU 1 is now offline
[ 134.958702] CPU 2 is now offline
[ 136.054832] CPU 3 is now offline
[ 137.148867] CPU 4 is now offline
[ 138.252997] CPU 5 is now offline
[ 139.455014] CPU 6 is now offline
[ 140.561271] CPU 7 is now offline
[ 140.570979] SMP alternatives: switching to UP code
Booting with noreplace-smp makes everything work fine. Maybe it's a new
bug in 2.6.30 ?
Mathieu
