Mi aiutate a capire da cosa è causato questo Kernel Panic?

[cippa lippa]

Ragazzi come da titolo. Sempre perfetto, oggi lo accendo e mentre vedevo un video su youtube mi da una serie di righe orizzontali sull oschermo di vario colore e due biip inframmezzati da pause.
Lo riavvio e di nuovo dopo un pò un Kernel Panic. Metto qui il resoconto

Possono essere le ram?

Il problema è nato da mdworker, come puoi leggere qui

BSD process name corresponding to current thread: mdworker

È un processo legato a spotlight.

ahh ecco.. uhmm e secondo te cosa potrebbe essere?cioè da cosa può dipendere? MA soprattutto, che fare per risolvere?ora funziona, però...

ahh ecco.. uhmm e secondo te cosa potrebbe essere?cioè da cosa può dipendere? MA soprattutto, che fare per risolvere?ora funziona, però...

Capita ogni tanto, nulla di allarmante se non si ripete. Altrimenti prova a cancellare il database di Spotligh e lasciarlo in pace per un po' a reindicizzare...

[cippa lippa]

ah davvero?mai successo una volta...
quello che mi spaventa un pò è il fatto che la prima volta ho dovuto spegnerlo forzatamente perchè mentre vedevo un video mi sono apparse delle righe orizzontali diciamo di colore verde, era freezato tutto e emetteva due biip e pausa, due biip e pausa... sembrava quasi un comportamento anomalo della scheda video...la seconda volta riacceso invece perfetto e poi tac kernel panic mentre guardo un altro video...

Ora provo a indicizzare spotlight di nuovo,faccio un backup e lo ristresso per verificare...

ad altri comunque è successo?che cosa strana...

[Janky]

non hai staccato o attaccato poco prima qualche periferica usb?

[cippa lippa]

assolutamente no
