Do i own defective xeon-cpu's / mainboard / bios, or are dell's server not capable of running modern linux-xen-distros? Or is there any chance, that it really is a server-bios or software-bug in either xen oder kernel implementation of ioremp (and its descendant functions)?
From Dell, I'd like to primarily find out how to get the machine to print out
From Intel, I'd like to find out if there is any similar issue known (I don't seem to be able to spot anything related in the specification updates), or what
Unfortunately it looks pretty likely at this point that this is a CPU issue, as from all we know so far the problematic mapping is the first ever established for that (bus) address range, and as it's uncachable there ought not to be anything in the caches for it, and hence (as indicated before) clflush should be a no-op. I'd really like to hear Dell's (Sandeep?) and ideally also Intel's (Marc?) opinion here. the machine check related MSR values, since the hypervisor doesn't appear to get control through an MCE here. the would recommend for further analysis. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
