| Message-ID | <s7JBn-QG-5@gated-at.bofh.it> |
Recently we have a new report that, the harddisk can not resume on time due to firmware issues, and got a kernel panic because of DPM watchdog timeout. So adjust the default timeout from 60 to 120 to survive on this platform, and make DPM_WATCHDOG depending on EXPERT.
