Hi all,

My computer fails early at boot with a stack along the lines of:

kmem_cache_zalloc
kmem_cache_create
kmem_cache_init
start_kernel

eip is at cache_calloc_refill+0x3e1 which is the
slabp->colouroff = colouroff; in alloc_slabmgmt()

I've bisected it down to the x86_64-mm-cpa-kerneltext.patch and the

+ if (!pte_present(*kpte))
+ return 0;

part in particular. Dotconfig and cpuinfo are available at
http://fdeweerdt.free.fr/kmem_prob/. Any ideas?

Regards,
Frederik
