Description yanshuang.zheng 2010-06-25 08:14:09 UTC

When starting installation OS based on kernel-2.6.35 with Intel wifi link 5100(driver in use: iwlagn) plugged, it immediately runs into kernel panic.

If unplug the wifi card, the installation can be started successfully. 

This is NOT found on kernel-2.6.34 and before.

Perhaps you could capture the console message?  Even a digital picture of the screen would be helpful.

Hard to tell, but that looks like grub to me.  Are you sure the kernel has even been loaded yet?

... please also remove the "quiet splash" from your boot command line so that we can see the full panic.

 I found this with kernel-2.6.35~rc3-118, but NOT any more with kernel-2.6.35~rc3-121.
