Next thing is to configure linux to write dmesg buffer to pstore when panicing, and the important thing is to panic. Add to command line: nmi_watchdog=panic,auto panic=5 softdog.soft_panic=5 (5 on the command line means 5 seconds) Unfortunately, in many suspend/hang issues nothing gets written to pstore because CPU is not available. Pstore is a last resort thing, a bit like console: it might help, or it might stay silent.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
