Hello again, I tried setting up netconsole (I don't have a null-modem serial cable with usb adaptor) and although it *does* capture some of the dump, it does not capture everything. The dump is from 3.18.5. Here goes (from the USB connection): [ 169.827703] usb 2-1.2: new high-speed USB device number 3 using ehci-pci [ 169.980222] usb-storage 2-1.2:1.0: USB Mass Storage device detected [ 169.982264] scsi host6: usb-storage 2-1.2:1.0 [ 169.984548] usbcore: registered new interface driver usb-storage [ 169.989296] usbcore: registered new interface driver uas [ 170.989458] scsi 6:0:0:0: Direct-Access WD My Passport 0748 1016 PQ: 0 ANSI: 6 [ 170.992673] scsi 6:0:0:1: Enclosure WD SES Device 1016 PQ: 0 ANSI: 6 [ 171.002766] sd 6:0:0:0: [sdb] Spinning up disk...
