I am hitting this issue because I enabled SMP for dom0 (found it is not working) and disabled it again. By doing so, the config file for dom0 kernel got changed like this. And I started seeing the hang. --- config.default 2005-08-19 23:04:51.560459168 -0700 +++ config.issue 2005-08-19 23:03:57.054745296 -0700 @@ -1,7 +1,7 @@ # # Automatically generated make config: don't edit # Linux kernel version: 2.6.12-xen0 -# Wed Aug 3 09:54:56 2005 +# Fri Aug 19 22:58:21 2005 # CONFIG_XEN=y CONFIG_ARCH_XEN=y @@ -143,14 +143,11 @@ CONFIG_MTRR=y CONFIG_HAVE_DEC_LOCK=y # CONFIG_REGPARM is not set -CONFIG_X86_LOCAL_APIC=y -CONFIG_X86_IO_APIC=y # # Bus options (PCI, PCMCIA, EISA, MCA, ISA) # -CONFIG_X86_UP_APIC=y -CONFIG_X86_UP_IOAPIC=y +# CONFIG_X86_UP_APIC is not set CONFIG_PCI=y # CONFIG_PCI_GOBIOS is not set # CONFIG_PCI_GOMMCONFIG is not set @@ -160,7 +157,6 @@ CONFIG_PCI_DIRECT=y CONFIG_PCI_MMCONFIG=y # CONFIG_PCIEPORTBUS is not set -# CONFIG_PCI_MSI is not set CONFIG_PCI_LEGACY_PROC=y # CONFIG_PCI_NAMES is not set # CONFIG_PCI_DEBUG is not set @@ -541,7 +537,7 @@ # CONFIG_IP_NF_MATCH_STATE is not set # CONFIG_IP_NF_MATCH_CONNTRACK is not set # CONFIG_IP_NF_MATCH_OWNER is not set -CONFIG_IP_NF_MATCH_PHYSDEV=y +CONFIG_IP_NF_MATCH_PHYSDEV=m # CONFIG_IP_NF_MATCH_ADDRTYPE is not set # CONFIG_IP_NF_MATCH_REALM is not set # CONFIG_IP_NF_MATCH_SCTP is not set @@ -1275,5 +1271,3 @@ # CONFIG_DEBUG_STACK_USAGE is not set # CONFIG_DEBUG_PAGEALLOC is not set # CONFIG_4KSTACKS is not set -CONFIG_X86_FIND_SMP_CONFIG=y -CONFIG_X86_MPPARSE=y Thanks & Regards, Nitin ----------------------------------------------------------------------------------- Sr Software Engineer Open Source Technology Center, Intel Corp -----Original Message----- From: Kamble, Nitin A Sent: Friday, August 19, 2005 6:49 PM To: Ian Pratt; xen-devel Subject: 32bit dom0 is hanging with changesset 6290 I am trying to debug this it.
