Hi, I am trying to figure out which cisco-vpn-client works and does not kill my running kernel (blinking keyboard LEDs very soon after some network traffic comes through the tunnel). With recent kernel like 2.6.31.14 with Gentoo package versioned cisco-vpnclient-3des-4.8.02.0030-r1 the hard-lock is that serious that mostly nothing is logged in time. I will try to find some computer with serial port to attach a remote console to. The only hint I found that once there was logged a single line like: eth0: Out-of-sync dirty pointer, 3835 vs. 3840. I went for older version of the cisco client and lower kernel series. Now it works for me for few hours already with some traffic but hey, I see this message again and luckily, the machine still runs. Therefore I am reporting this bug here as I hope same issue exists in current more kernels although with more drastic consequences.
