Public bug reported:
I have been noticing frequent system hang for more than a month on my
Laptop(G580). However the frequency increased to every 30-45 min recently.
I can't generate a crash after the hang as nothing works, I have to do a hard
reboot.
I tried to generating a crash using Ctrl’+'Alt’+'SysRq’+1 followed by
Ctrl’+'Alt’+'SysRq’+t, but no use. Finally I had to do a hard reboot.
Please help me fix this issue; Do let me know if you need any help from
me.
The following are the system and package information of my laptop
