Kernel nebo ntp?

[Filip Hroch]

Ciao

to je hlaska kernelu. Obecne se daji rict dve veci:

1. chyba je v kernelu, pokud mas nejakou starsi verzi
   bylo by vhodne updatovat

2. chyba je v HW, pokud pocitac delsi dobu slapal jak
   hodinky a ted se z niceho nic zacina sam resetovat
   pri beznych funkcich nebo takhle podivne pada zacina
   neco odchazet, nejspise vetracek.
