Perhaps the fact that you have *two* cards in each machine that crashes with the 8139too driver could be important? I have two Athlon XP 2000+ with Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ that distcc quite a lot, and never any crash. But network topology and timings might just trigger the panic in your situation and not with others...

Yeah, although that viewpoint might not be very popular on this mailing list. ;-) By the way the patch looks quite alright and applies (with an offset) to 2.6.5 as well. If you build 8139too modular, you might even make two modules, a modified one with the reduced advertised capabilities (so that the kernel assumes the card isn't zero-copy capable) under another name perhaps like 8139too-nosendfile, and the standard one. You can than at least distribute one kernel package, and only on the affected machines modprobe the bugfix module.
Anyway, first installing a distcc without sendfile() usages, can make you (distcc)build patched kernels much faster in the future. ;-) -- Marco Roeland - 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/
