When # making buildworld (freshly updated stable), it coredumps with a signal # 11 at different stages, usually after around 10 minutes, shortly after # the fan kicks in. # # I know this is usually either a heat or a bad memory issue, but before # I send it back, I would like to know if there are any known issues # with P4 Dell notebooks, not particularly related to heat. Could it be # that FBSD has problems with a P4 system? Or is this definitely a # heat/memory issue. How do your P4 Dell notebooks behave? # # I will also reinstall win xp that came with the notebook and see if I # can produce any errors there, I will check google for apps that # generate cpu-load and display system temperature or any anomalies. Many of the laptop manufacturers have been known to use the desktop version of the Pentium 4 processor in their laptops (opposed to the mobile version of the Pentium 4 processor). The desktop version does not have some of the power saving (and probably temperature control) features that the mobile version does... and it pumps out more heat than the comparable mobile version of the processor. The heat problem in some of the laptops that use the desktop Pentium 4 processor also causes more stability problems under Windows as well as any other OS (like Linux). Some of the more problematic laptops are from HP/Compaq and Toshiba... but I haven't heard or seen any reports of the Dell laptops exhibiting the same problem. One thing that I would try is to do a long load test under Windows XP that pelts the processor and memory. I don't know of any ports that would do the same thing as say 3DMark or other benchmarking software under FreeBSD. -- Linh Pham lplist@closedsrc.org Webmaster and FreeBSD Geek http://closedsrc.org closedsrc.org Every solution breeds new problems To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
