Date: Sun, 14 Aug 2011 13:08:28 +0200 From: Kjun Chen <kjun-chen@...bodha.org> To: netdev@...r.kernel.org Cc: romieu@...zoreil.com, nic_swsd@...ltek.com Subject: r8169 hard-freezes the system on big network loads Hi, as I have mentioned to linux-kernel, this is perfectly reproducible: receiving 70 MB/s or more freezes my laptop (Dell Vostro, amd64, 6 GB RAM, 8x Intel Core i7 CPU Q 740 @ 1.73GHz) completely, sometimes within seconds, sometimes only after a minute. Watching the normal console I get loads of r8169 0000:13:00.0: eth0: link up r8169 0000:13:00.0: eth0: link up [...] one message about every 1-2 seconds (sometimes even 2 per second) while network is active on 2.6.37.6. Up to the latest kernel (3.0.1) this freeze happens. However, 2.6.32.28 works with no problems, and it doesn't show those "eth0: link up" messages. I haven't tried kernels between .32 and .37. lspci says: 13:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03) The solution with 2.6.37 and above: use the r8168 module from the realtek website. I have tested it with >30 GB at rates of 112 MB/s and experienced no freezes anymore. If you need any other information or help, please let me know. cheers, Michael -- Sambodha: The Return of True Self-Knowledge -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
