at least I could do some pretty dirty things to the poor chip and it still seems to recover after this patch. rmmod still has some problems, occasionally I get a "usage count 2" thing (currently running the rawhide 2.4.22-1.2061.nptl, I've seen similar with 2.6.0-test5ish too, I suspect ipv6 might be involved, but sometimes I can rmmod it even with ipv6 loaded so it's a bit random). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
