RE: [Xen-users] Xen 3.1 kernel panics on RHEL4u5

["Apparao, Padmashree K" <padmashree.k.apparao@xxxxxxxxx>]

If the boot drive is a SATA then you must build it into the kernel, not as a module

 

Such as CONFIG_SCSI_SATA=y

 

Make all the SATA related as “y” in the .config  and rebuild your xen kernel. If they are built as modules they will not be loaded until the kernel is booted (and of course the kernel cannot boot w/o SATA)

Subject: [Xen-users] Xen 3.1 kernel panics on RHEL4u5

 

Hello,

 

I am trying to install Xen 3.1 (with Linux kernel 2.6.18) from source on a machine running RHEL4u5 (2.6.9-55.ELsmp), but I am getting kernel panics.  I've listed the KPs below.  The first listing is with an initrd image specified, and the second one is without an initrd image.  For the second listing, I am only including the portion that differs from the first.

                                              
With initrd image:

Some of the threads I've seen indicate that missing SATA support might be the culprit, but the SATA portions of my kernel configuration files seem to be identical in the relevant areas:

 

RHEL Kernel configuration:

# CONFIG_BLK_DEV_IDE_SATA is not set
# CONFIG_BLK_DEV_HD_IDE is not set
...
CONFIG_ATA=m
CONFIG_SATA_AHCI=m
CONFIG_SATA_SVW=m
CONFIG_ATA_PIIX=m
CONFIG_SATA_MV=m
CONFIG_SATA_NV=m
CONFIG_PDC_ADMA=m
CONFIG_SATA_QSTOR=m
CONFIG_SATA_PROMISE=m
CONFIG_SATA_SX4=m
CONFIG_SATA_SIL=m
CONFIG_SATA_SIL24=m
CONFIG_SATA_SIS=m
CONFIG_SATA_ULI=m
CONFIG_SATA_VIA=m
CONFIG_SATA_VITESSE=m
CONFIG_SATA_INTEL_COMBINED=y

Xen Linux configuration from xen-3.1.0-src/build-linux-2.6.18-xen_x86_64:

# CONFIG_BLK_DEV_IDE_SATA is not set
# CONFIG_BLK_DEV_HD_IDE is not set
...
CONFIG_SCSI_SATA=m
CONFIG_SCSI_SATA_AHCI=m
CONFIG_SCSI_SATA_SVW=m
CONFIG_SCSI_ATA_PIIX=m
CONFIG_SCSI_SATA_MV=m
CONFIG_SCSI_SATA_NV=m
CONFIG_SCSI_PDC_ADMA=m
CONFIG_SCSI_HPTIOP=m
CONFIG_SCSI_SATA_QSTOR=m
CONFIG_SCSI_SATA_PROMISE=m
CONFIG_SCSI_SATA_SX4=m
CONFIG_SCSI_SATA_SIL=m
CONFIG_SCSI_SATA_SIL24=m
CONFIG_SCSI_SATA_SIS=m
CONFIG_SCSI_SATA_ULI=m
CONFIG_SCSI_SATA_VIA=m
CONFIG_SCSI_SATA_VITESSE=m
CONFIG_SCSI_SATA_INTEL_COMBINED=y

My grub.conf (with initrd specified):

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux ES (2.6.9-55.ELsmp)
 root (hd0,0)
 kernel /vmlinuz-2.6.9-55.ELsmp ro root=/dev/sda3 rhgb quiet
 initrd /initrd-2.6.9-55.ELsmp.img
title Red Hat Enterprise Linux ES-up (2.6.9-55.EL)
 root (hd0,0)
 kernel /vmlinuz-2.6.9-55.EL ro root=/dev/sda3 rhgb quiet
 initrd /initrd-2.6.9-55.EL.img
title Xen 3.0 / XenLinux 2.6
 root (hd0,0)
 kernel /xen-3.1.gz dom0_mem=262144 com1=115200,8n1 console=com1
 module /vmlinuz-2.6.18-xen root=/dev/sda3 ro console=ttyS0,115200
 module /initrd-2.6.18-xen.img

 

Does anyone have any idea of what might be causing the kernel panics?

 

Thanks,

-Ryan
