| |
Hi, during my normal work (playing mp3, grabbing teletext (and copying teletext data to netware), pinging some important local hosts, running Netware test server inside vmware), I got following three oops. First is some problem with kmem_cache_free: slabp was NULL in check (mm/slab.c:1569): if (slabp->s_magic != SLAB_MAGIC_ALLOC) goto bad_slab; other were deadlocks on &cachep->c_spinlock lock (first in kmem_cache_free, second in kmem_cache_reap; after that both CPUs died). As I do not understand current memory allocator, I'm out of ideas. Maybe I should download Ingo's patches to MM just now. Before these oops machine was up for almost 24hrs.
