Hali,
Azert ebbe a topicba irom, mert gentoot hasznalok a gepen, habar nem hinnem hogy a disztribucionak sok koze lenne a kernel hibahoz, de azert mindennek fen all az eselye:
A gep:
Linux localhost 2.6.15-gentoo-r1 #1 SMP Tue May 16 21:48:04 CEST 2006 i686 AMD Athlon(tm) XP 1600+ GNU/Linux
A problema elofordulasa, nem periodikus, valamikor 1hetig megy a gep, valamikor 2napig, eloidezni sem tudom, bar lehet rossz fele probalkozom.
A kod a /var/log/messages-bol:

Tovabba iptables modulokra is panaszkodik neha.
Es anno xfs modulra is ugyanezt csinalta, azota reiserfs-re csereltem mindet, es tobbet nem fordult elo ilyen.
A wiki-n olvastam egy cikket,meg itt a forumban is jo parat, amibol kiderul h a problema forrasa valoszinu a memcpy, de keves programozoi ismeret hianyaban az assemblyben, nemtudom pontosan megtudni mi is a problema valos oka.
Talalkozott mar valaki ilyen problemaval?
Mi lehet a megoldasa? sw vagy hw problema volna a hatterben?
