[Bug 448827] Re: r8169 driver causes CPU soft lockup

[Hugh Cole-Baker]

I upgraded to the 10.04 Beta version, and the bug was still present. I ran apport under 10.04 to get updated info, then tried the mainline kernel (2.6.34-999-generic #201004051003), but the bug still happens. 
It is quite easy for me to reproduce, just boot up the system, connect it via built-in Ethernet, leave it, then SSH in and run any networking-intensive task and it will eventually freeze up with no response over the network or on the console.
After it has frozen it will only respond to the magic SysRq keys, but there seems to be no way to get it back into a usable state. All I can do is print debugging info to the console, and since it's only 640x480 there isn't much use as the screen's too small to read the backtrace(s). None of the debugging info gets saved to /var/log/, presumably because the rest of the kernel is locked up.
