Hi, it seems that I might find one possible "trigger" of this bug: heavy download. Today I'm trying to download a big file with wget, and this bug occurs six times before I could not bear it any more (every time I have to reboot to recover my network!) and bought a network cable downstairs in the supermarket and used wired network instead. It seems that when downloading at full speed (20 Mbps fiber, ~2.3 MiB/s) for several minutes and the bug, very possibly, may occur. Several days ago, when I tried to download "linux-3.12.tar.xz" from kernal.org with wget, the bug also occured twice during the whole download process. Could this be a hardware issue (flawed hardware?) or just driver issue? I bought this laptop 8 days ago and wiped the pre-installed Windows the moment I got it, so I have no idea how this wireless card performs under Windows. -- wzyboy -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
