Bug#372523: linux-image-2.6.16-2-xen-686: kernel panic on software raid (md0)
Hello, I actually found what the problem is, and i wonder if it is related to your kernel settings. When i perform an install of Debian, the installer sees two IDE drives as hda and hdc (they are indeed connected as primary and secondary master) and a CDrom drive. When your Xen kernel boots, it then sees the two drives as hde and hdg, which doesn't really make sense. The server is a Dell PowerEdge 650 which has been stripped of all SCSI drives and being used with IDE instead. The IDE controller seems to be a secondary controller from the looks of it therefore explaining that devices are being *moved* to hde and hdg. Now, why would the Debian installer see them as hda and hdc puzzles me a bit. I hope that will help you out, i'm surely not the only one wanting to install Xen on such a configuration.

The question is: what is being seen as the primary IDE controller in this case (which claims hda-hdd). This is all about the order in which device driver modules are being loaded and, basically, you cannot depend on any order. This is also the reason behind the erratum for d-i listed on: http://www.us.debian.org/devel/debian-installer/errata Cheers, FJP pgpFLEQihyMKv.pgp Description: PGP signature

The question is: what is being seen as the primary IDE controller in this case (which claims hda-hdd). The IDE controllers on the box are : 00:05.0 IDE interface: Silicon Image, Inc. PCI0680 Ultra ATA-133 Host Controller (rev 02) 00:0f.1 IDE interface: Broadcom CSB6 RAID/IDE Controller (rev a0) On normal debian install/kernel, the broadcom gets loaded first. On the Xen kernel; the Sil controller gets in first. Interestingly, the only way i got the Xen kernel to boot was to use yaird rather than the standard mkinitrd, that is the only one which compiles a proper list of my modules. This is also the reason behind the erratum for d-i listed on: http://www.us.debian.org/devel/debian-installer/errata Nice one, i had forgotten about that one, that would indeed explain the behavior. I have to paste this in, this is the boot from the Xen kernel : SiI680: IDE controller at PCI slot :00:05.0 SiI680: chipset revision 2 SiI680: BASE CLOCK == 133 SiI680: 100% native mode on irq 16 ide0: MMIO-DMA , BIOS settings: hda:pio, hdb:pio ide1: MMIO-DMA , BIOS settings: hdc:pio, hdd:pio Probing IDE interface ide0... hda: SAMSUNG SP2014N, ATA DISK drive ide0 at 0xf4802080-0xf4802087,0xf480208a on irq 16 Probing IDE interface ide1... hdc: SAMSUNG SP2014N, ATA DISK drive [snip] SvrWks CSB6: IDE controller at PCI slot :00:0f.1 SvrWks CSB6: chipset revision 160 SvrWks CSB6: not 100% native mode: will probe irqs later ide2: BM-DMA at 0x08b0-0x08b7, BIOS settings: hde:DMA, hdf:pio ide3: BM-DMA at 0x08b8-0x08bf, BIOS settings: hdg:pio, hdh:pio Probing IDE interface ide2... hde: TEAC CD-ROM CD-224E, ATAPI CD/DVD-ROM drive It actually booted up properly BUT (that's the important bit here), GRUB wanted this to be able to start : title Xen 3.0 / XenLinux 2.6 kernel /xen-3.0-i386.gz noreboot module /vmlinuz-2.6.16-2-xen-686 root=/dev/hde1 ro module /initrd.img-2.6.16-2-xen-686 Steph - -- Mail sent on Gentoo Linux (http://www.gentoo.org) http://frlinux.net - [EMAIL PROTECTED] public key : http://frlinux.net/files/frlinux_public_key.asc -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.2.2 (GNU/Linux) iD8DBQFElv7xplbM2wjOZgMRAkp3AJ9P+Hi/Fm50tE4NBBhSVxDi0qMkpwCgs1zh dy6ScXWtuJDlVod6JDI/I7s= =yWS5 -END PGP SIGNATURE- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Why do you expect that a xen image may boot different from a standard one? That's it, i don't expect it to be different and the standard image does handle all my soft raid properly.
