Leann, Thanks. Looking at this in a virtual terminal, I can establish that this is a suspend problem, and I can repeat it. But it's a slightly unusual one, and only occurs when I am using a USB 3G modem. Of course, I do that almost every day when commuting by train, so that it's not unusual for me.
Steps to repeat: (1) Establish a wireless connection with USB modem. (2) Remove modem without formally shutting down network-manager - just grab and yank (the train is entering a station) (3) shut lid on laptop. Expected action: the laptop suspends. Actual action: the laptop hangs, and cannot be made to suspend by keypress or resume on lid opening. Only a forced shutdown (with the power button) works, and that leads, on restart, to the crash report here noted. WORKAROUND (not actually practical, but informative) Following the advice on the debugging page you pointed me at, I tried this with a virtual terminal open. Working that way, "sudo pm-suspend" works normally unless the usb modem has been removed (see above). When that happens, a message appears on the VT saying eg "[5766.522282] option: option_instat_callback: error -108" Attempting to suspend while that message remains on screen leads to the same hang as before. However, if I press the cursor-up, thus recalling the previous "sudo pm-suspend" command, and then press enter, that works. Is this helpful? Should the bug be reclassified?
