Under -rc5-mm2, this works fine. For -rc7-mm[12], it finds the disk: ata_piix 0000:00:1f.2: version 2.11 ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ] ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 17 (level, low) -> IRQ 17 PCI: Setting latency timer of device 0000:00:1f.2 to 64 scsi0 : ata_piix scsi1 : ata_piix ata1: SATA max UDMA/133 cmd 0x00000000000101f0 ctl 0x00000000000103f6 bmdma 0x000000000001bfa0 irq 14 ata2: PATA max UDMA/100 cmd 0x0000000000010170 ctl 0x0000000000010376 bmdma 0x000000000001bfa8 irq 15 ata1.00: ata_hpa_resize 1: sectors = 156301488, hpa_sectors = 156301488 ata1.00: ATA-7: ST980825AS, 8.04, max UDMA/133 ata1.00: 156301488 sectors, multi 8: LBA48 NCQ (depth 0/32) ata1.00: ata_hpa_resize 1: sectors = 156301488, hpa_sectors = 156301488 ata1.00: configured for UDMA/133 ata2.00: ATAPI, max UDMA/33 ata2.00: configured for UDMA/33 scsi 0:0:0:0: Direct-Access ATA ST980825AS 8.04 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 156301488 512-byte hardware sectors (80026 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 0:0:0:0: [sda] 156301488 512-byte hardware sectors (80026 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sd 0:0:0:0: [sda] Attached SCSI disk sda1 is an ext3 /boot, sda2 is an LVM space covering the rest of the disk, so we're doing well so far. The 'lvm vgscan' fails and says 'No volume groups found, with no useful kernel messages issued. Then we get the infamous "Kernel panic - not syncing: Attempted to kill init!" when it can't find the root file system and we fall off the end of the initrd. Any ideas?
