Tdenham। मेरी भी यही स्थिति है। मैंने अभी सिस्टम को 14.04 से 16.04 तक अपडेट किया है do-release-upgrade -d
।
यदि आपके पास सिस्टम तक सीधी पहुंच नहीं है, और आपको वास्तव में रिबूट करने की आवश्यकता है, तो आप वर्कअराउंड के रूप में हार्ड रीसेट की कोशिश कर सकते हैं (जैसा कि यहां वर्णित है: https://major.io/2009/01/29/linux-emerarios- रिबूट-या-शटडाउन-विद-मैजिक-कमांड / )
echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger
जो चाल करता है। संभवतः आपको sync
दूसरी कमांड से ठीक पहले चलना चाहिए ।
reboot -f
मदद कर सकते हैं, लेकिन मैं यह कोशिश नहीं की के रूप में मैं सर्वर का उपयोग नहीं कर सकता अगर यह फिर से लटका हुआ है।
आप / var / log / syslog फ़ाइल की जाँच कर सकते हैं। उस जगह का पता लगाएं जहां आप कंप्यूटर चालू करते हैं और उससे ठीक पहले लाइनों की जांच करते हैं। आप इसे यहाँ पेस्ट कर सकते हैं।
मेरा syslog:

ऐसा लगता है कि रिक्वेस्ट रिक्वेस्ट करने पर भी dhclient ip एड्रेस को प्राप्त करने की कोशिश करता है।
मामले में यह एक हार्डवेयर पर निर्भर मुद्दा है जिसका मैंने उत्पादन किया है lspci
, जिससे इसे परेशान करने में मदद मिल सके।
