This seems to be what's triggering the apparent memory corruption we've been seeing recently -- in the case of the Fedora kernel it manifests itself as a BUG() in cache_alloc_refill() when the pmac ide driver initialises. Another report was at http://lkml.org/lkml/2006/12/17/4 We've been seeing it on a Mac Mini too, and I managed to reproduce it on my shinybook this evening by booting with 'mem=512M'. One side-effect of this patch is to move the call to free_initrd() much later in the init sequence, potentially after other memory management code is assuming it's already been freed. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
