I can see the crash everytime on my lenovo x201 (x86 64bit, i5) with this wireless chip: [ 19.484551] iwlagn 0000:02:00.0: Detected Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74 As I'm travelling I only have two bad quality screenshots and 40 MB video of the crash :) From the stacktrace it looks that this is iommu related: http://www.adurom.com/~kvalo/tmp/iwlagn/rmmod-iommu-crash/1.png http://www.adurom.com/~kvalo/tmp/iwlagn/rmmod-iommu-crash/2.png This is a new laptop and most likely I haven't removed iwlagn module before. So this shouldn't be a regression. -- Kalle Valo
