https://bugzilla.suse.com/show_bug.cgi?id=1184817 https://bugzilla.suse.com/show_bug.cgi?id=1184817#c37 --- Comment #37 from Takashi Iwai <tiwai@suse.com> --- If the system is screwed up by the enablement of an Ethernet device, the possible cause is either too many (unhandled / handled) wild interrupts or memory corruption or such bug. Usually the latter should be visible in the kernel log as a kernel crash, while the former isn't always seen -- especially if the irq table is already suspicious (the dead irq 9 was reported). If the interrupts go crazy, everything can happen, no matter which I/O. The fact that web browser doesn't open implies that something is blocked, and it could be a network. I have no grasp how many bugs you already submitted and all smell really like the same cause. When the problem happens, and when you unplug the USB Ethernet device (instead of power-off / reset), does the problem persist? -- You are receiving this mail because: You are the assignee for the bug.
