[LUGOS] FC2 & unable to handle kernel paging request

[Ales Smrdel]

Lep pozdrav!

Zanima me, ali je kdo ve, v cem bi lahko bila tezava. V petek sem se odlogiral, 
racunalnik pa pustil prizgan. Stvar je ocitno delala se kaksni 2 uri, nato pa 
je ocitno prislo do tezav s kernelom, tako da je racunalnik zamrznil. Vceraj 
sem ga resetiral in stvar je nato normalno delala do (po logih) 22h, 
kjer se je ponovila podobna napaka (ista napaka, drugi proces). 
Ali morda kdo ve, v cem bi lahko bila tezava? 
Racunalnik je 
Celeron na 2.67GHz, z 512MB RAM-a in Radeon 9250 graficno kartico, 
sistem jf Fedora Core 2 (full instalacija) brez kakrsnih koli posodobitev.
Malo sem ze gledal po googlu, pa nisem nasel nic uporabnega. Za kakrsno koli 
pomoc bi bil prav hvalezen.

Ales

Tukaj pa je se izpisek loga od trenutka, ko je prislo do napake pa do trenutka, 
ko sem resetiral racunalnik (petek-ponedeljek), novejsi izpis je podoben, le 
da je namesto sendmail programa xscreensaver:
