49 63 c4 movslq %r12d,%rax 48 8b 54 c2 18 mov 0x18(%rdx,%rax,8),%rdx [objdump is broken, opcode 49 63 is actually movsxq] r12 == 0000000000000032 rax == 2000000000000032 This looks like a broken CPU to me: the bottom 32 bits of r12 were moved with sign extension to rax but one bit is now wrong in rax. Yesterday i ran the full Dell hardware test for PE 1800 (i executed it in extended mode) and all was ok, no errors. Is there another tool I can test the CPUs with? Do you think that the Dell Test Tools might not be able to detect such an error?

You can run it by booting the Fedora install CD/DVD and selecting it. Also: http://www.ibm.com/developerworks/library/l-hw1/ Many people swear by this one but it could overheat the system: http://pages.sbcglobal.net/redelm/ (This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report! |
