[Xen-users] Kernel panic on booting 2.6.32.16 pvops kernel
Im currently running the xen 4.0.1-rc5-pre version with the linux 2.6.32.16
as the pvops kernel.
I get this kernel panic when booting into the dom0 :
[ 6.003753] Initializing CPU#0

Following is the grub config:
title Xen 4.0.1 Testing - Linux 2.6.32.16 pvops
root (hd0,0)
kernel /xen.gz noreboot loglvl=all guest_loglvl=all iommu=pv
console=tty1 console=com2 com2=57600,8n1
module /vmlinuz-2.6.32.16 ro root=/dev/vg1/root loglevel=10
swiotlb=force earlyprintk=xen xencons=ttyS1 console=ttyS1
module /initrd-2.6.32.16.img
savedefault 0
Im running this on a Dell R610 Poweredge Server with Intel X5550 processors.
Ive tried this with both swiotlb turned on and off. It gives the same kernel
panic. Any suggestions or ideas why this is happening?
Thanks,
Adit

It seems out of memory, you can try to add dom0_mem=512M after ''kernel /xen.gz'' On Thu, Jul 22, 2010 at 1:40 PM, Adit Ranadive <adit.262@gmail.com> wrote:> Im currently running the xen 4.0.1-rc5-pre version with the linux 2.6.32.16 > as the pvops kernel. > I get this kernel panic when booting into the dom0 : > > [ 6.003753] Initializing CPU#0 > [ 6.011036] DMA: Placing 64MB software IO TLB between ffff880020000000 - > ffff880024000000 > [ 6.011044] DMA: software IO TLB at phys 0x20000000 - 0x24000000 > [ 6.011047] xen_swiotlb_fixup: buf=ffff880020000000 size=67108864 > [ 6.018646] Kernel panic - not syncing: DMA(-12): Failed to exchange > pages allocated for DMA with Xen!
