Is this indeed only happening under Xen? If so, the difference to the native case would need to be investigated (i.e. open a bug, attaching the _full_ boot log of the kernel and hypervisor). If not, perhaps there's a BIOS setup option allowing more space for the needed MMIO ranges? Also without the full log it's hard to tell whether these are legitimate failures (taking into consideration the allocation strategy of the kernel), indications of bugs, or indications of that strategy needing improvement.

That's a hint at there indeed not being enough MMIO space, or the kernel not (always) falling back to using 64-bit address ranges when short on 32-bit ones. But again - nothing specific can be said without seeing the full log. And also again it should be made clear whether this is a problem with _only_ the Xen kernel.

Indeed this very much looks like what you need. But you want to adjust it towards the 1.0 Gb value, not the 3.25 Gb one. Jan -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Manually changing the TOLUD value Dynamic -> 1.0GB does leave the system bootable, but does NOT change the issue.

What problem/error conditions are caused by the above messages?

In my BIOS there was also a setting for PnP that allowed me to try different orders or disable some. I tried changing that once, and the above error list got a bit longer, but still finished. Maybe your bios has such a setting? Either that or try taking out any optional equipment from your computer (have you added any new HW recently?).. good luck....?
added 'pci=realloc'
cat /proc/cmdline root=... pci=realloc
recreated initrd & rebooted.
Unfortunately, it made it worse.

What are these errors, and what's a fix, if not the 'pci=realloc'?

Hi lyndat3, Do you mind to open a bug on openSUSE bugzilla? https://bugzilla.opensuse.org/index.cgi And, please attached on the following log: lspci -vvv (without pci=realloc) lspci -vt dmesg with "pci=earlydump" kernel parameter acpidump > acpidump.dat I can help to analysis those log and try to find out some hint. Normally the pci=realloc can walkaround some problem on BAR assigning fail because it should give pci bridge enough memory window for the pci devices behind the bridge. Thanks a lot!
