http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1726 ------- Comment #6 from shaohui.zheng@xxxxxxxxx 2011-01-31 18:36 ------- Copied from Fengzhe's email. In intel_i9xx_setup_flush (intel-agp.c), agp driver tries to map a "Flush Page" using ioremap_nocache(). But the I/O page address passed to ioremap_nocache() is not valid in both P2M and M2P tables. The page address is always 8MB over max dom0_mem. If I remove the ioremap logic, dom0 can boot successfully with no noticeable error. The bug is reproduced on HP 7800p machine with Core2 processor and Q35 motherboard. -- Configure bugmail: http://bugzilla.xensource.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. _______________________________________________ Xen-bugs mailing list Xen-bugs@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-bugs |
