--- Comment #24 from Jan Beulich
Further debugging the xen-version of ioremap, the more precise failing code-position is in /usr/src/linux/arch/x86/mm/ioremap-xen.c -> in function ioremap_change_attr() -> failing line: err = set_memory_uc(vaddr, nrpages);
Yes, that was the primary suspect, and provides the hint that it may be worth trying the 11.0 hypervisor on a 10.3 installation (I would expect it to cause the same kind of failure). Doing the inverse experiment (10.3 hypervisor below 11.0 kernel) would require the kernel config to be changed slightly: CONFIG_XEN_COMPAT_030002_AND_LATER would need to be turned on, CONFIG_XEN_COMPAT_030004_AND_LATER should instead be turned off, and that should result in CONFIG_XEN_COMPAT=0x030002 (would need to be verified manually - past experience shows that this doesn't always get adjusted as intended, but I didn't get around to check why). The question of course is whether you can afford this amount of experimentation. -- 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.
