Hi xiaolong,
Really thanks for your testing.

let's make the problem clearly firstly:
1) Commit 43436935b7 ("x86/xen: Bypass intr mode setup in enlighten_pv system") made kernel boot failed, which caused by OOM.
2) Commit 03fa63cc96 ("x86/time: Initialize interrupt mode behind timer init") can make the kernel boot success again, but with an ACPI error happened.
And both *1* and *2* used the same configuration showed in the attachment.
Does anything I missed?
Thanks,
dou.
