Zdravím vás,
už přes dva týdny se snažím vypořádat s náhodným zamrznutím nového PC, který slouží jako zálohovací stanice.
Někdy běží 3 dny v kuse bez problému, raid5(mdadm), rsync, samba, tar, cron, všechno v pořádku a najednou lehne. Jindy nevydrží běžet ani půl dne.
PC to dělá již od začátku. Vyzkoušel jsem různé distribuce s ruzným jádrem 3.x i 4.x a stále stejné chování.
Tipuju nějakou HW závadu, ale nevím kde začít a zda to nemůže být ještě někde jinde.
lshw je v příloze
Nemá někdo nápad, prosím?
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial
Server verze bez GUI
