the sched_init() slab corruption bug is still there, i just triggered it
on two separate test-systems:
[ 0.510620] CPU1 attaching sched-domain:
[ 0.512007] domain 0: span 0-1 level CPU
[ 0.517730] groups: 1 0
[ 0.520528] =============================================================================
[ 0.524002] BUG kmalloc-8: Wrong object count. Counter is 11 but counted were 50
[ 0.524002] -----------------------------------------------------------------------------
[ 0.524002]
i've pushed out that specific tree: tip/tmp.cpus4096-v2.broken, which
you should be able to reproduce via:
git remote update
git checkout -b tmp.test tip/tmp.cpus4096-v2.broken
config attached. This config should just run through a 'make oldconfig'
fine and if the bzImage is built, it should produce the slab corruption
messages on any typical 64-bit PC. I've attached the boot log below as
well. (You can see the gcc version i used in the bootup log as well.)
I'll disable MAXSMP in these testruns - just to establish the stability
without any of the dynamic-cpumask_t stuff.
