Issue is not seen with latest kernel from 20050830 ... P. Ouch ... this is being caused by slab corruption -- the BUG was triggered by: static void check_slabp(struct kmem_cache *cachep, struct slab *slabp) { kmem_bufctl_t i; int entries = 0; /* Check slab's freelist to see if this obj is there. */ for (i = slabp->free; i != BUFCTL_END; i = slab_bufctl(slabp)[i]) { entries++; if (entries > cachep->num || i >= cachep->num) goto bad; } if (entries != cachep->num - slabp->inuse) { bad: printk(KERN_ERR "slab: Internal list corruption detected in " "cache '%s'(%d), slabp %p(%d). Hexdump:\n", cachep->name, cachep->num, slabp, slabp->inuse); for (i = 0; i < sizeof(*slabp) + cachep->num * sizeof(kmem_bufctl_t); i++) { if (i % 16 == 0) printk("\n%03x:", i); printk(" %02x", ((unsigned char *)slabp)[i]); } printk("\n"); BUG(); } } P. Clarifying comment #1: The issue only seems to hit during the installation -- I can load the kernel via rpm and boot without any issues. Changing to proper owner, kernel-maint. |
