Those two cores still share the same memory space. If a certain kernel thread wrote to some unexpected in the kernel memory space, you'll have problems later on. If a kernel thread existed unexpectedly and left some resources in use, you may have a problem recovering. > > Jan 15 14:45:17 test kernel: WARNING: at arch/x86/kernel/hpet.c:390 > > hpet_next_event+0x5c/0x81() (Not tainted) But as Muli already noted, this is a warning, rather than a 'BUG'. The kernel code in question did continue execution. -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il | | a Mutt's tzaf...@cohens.org.il | | best ICQ# 16849754 | | friend _______________________________________________ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
