Ezert szerencses az akinek Cortex A7 procis telefonja van : http://www.samsung.com/hu/consumer/mobile-devices/smartphones/others/GT… :)

Annyira "buta" proci, hogy nem erinti a problema. :)

Lenovo TAB 2 A8-50 : MT8161 => Cortex A53 szinten nem erintett! :)

Fingers crossed!

According to IBM, firmware patches for POWER7+, POWER8, and POWER9 platforms are all currently available via FixCentral. The company says Power7 patches will be available February 7. In addition, it estimates IBM i operating system patches (also available via FixCentral) will finish rolling out on February 12, and AIX patches will be available starting January 26.

If the alternative was a two-decade product recall and giving everyone
free CPUs, I'm not sure it was entirely insane.

Certainly it's a nasty hack, but hey — the world was on fire and in the
end we didn't have to just turn the datacentres off and go back to goat
farming, so it's not all bad. ..."

A Metrics meg nem muxik ...

Holnap sima Ellasticsearch, stb. 5.5.1-os verzio lesz sima Dockeren tesztelve ...

4.4.76-1-default kernellel az Nvidia driver 384.59 egy rakas k@ki. => Intelre kenyszerultem.
Ez legalabb muxik. Kip-kop.

4.4.79-19-default kernellel es Nvidia drivert kezimunkazva mukodik.

A 4.4.85-22-default kernellel mar OK a gfxG04-kmp-default-384.69_k4.4.76_1-25.1.
