Searching nonpaged pool (ffffc48000000000 : ffffd48000000000) for tag 0x3f707249 (Irp?)

Co nepomohlo:
  • odinstalovanie wifi - teda zakaz a nasledne odobratie, lebo odobratie priamo nikdy neskonci
  • zakaz wifi v device manageri
  • postupna instalacia 3 roznych driverov pre wifi
  • zakaz power managementu PCIe
  • zakaz power managementu wifi
  • zakaz fast boot
  • citanie syslogu

Trochu pomohol safe mode, po nom to nepada. Inak je to cele reprodukovatelne a vzdy to padne v vwifibus.sys.
Nejaky tip, ako sa to debuguje? Prip. ako zistit, co tomu je? Na Googli som nic nenasiel.
