Hi Christoph,
last night I got an interesting backtrace running 3.0-rc3 (Fedora Rawhide kernel package). Unfortunately netconsole seems to be incompatible with KVM at the moment, so I had to capture the oops on my digital camera and will be transcribing just the backtrace.
Essentially, kernel 3.0-rc3 hit this bug:
static int check_slab(struct kmem_cache *s, struct page *page) { int maxobj;
VM_BUG_ON(!irqs_disabled());
The call trace:
check_slab alloc_debug_processing __slab_alloc kmem_cache_alloc bvec_alloc_bs bio_alloc_bioset bio_alloc mpage_alloc do_mpage_readpage ... followed by ext4 and VFS code, obviously innocent
Is this a known issue, Christoph?
If not, anything I can do to help debug/fix this?
