Distribution: Gentoo gentoo-dev-sources 2.6.9-r1 Hardware Environment: I-Will DK8N w/ nForce3 250 Software Environment: see .config attached Problem Description: If I compile the kernel with Windows Logical Disk Manager support, I get a kernel panic on boot. I have not tried other Advanced Partition types. I have tried where my boot drive is PATA, SATA using deprecated support, and SATA using libata. I have not tried on x86. snips from dmesg when boot drive is on SATA using libata. similar messages occur for other scenarios: scsi1 : sata_nv . . . drive details . . . SCSI device sda: . . . more details . . . SCSI device sda: drive cache: write back /dev/scsi/host0/bus0/target0/lun0: unknown partition table . . clipped dmesg . . VFS: Cannot open root device "sda3" or unknown-block(8,3) Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on sda3 The same issue also seemst to be discussed in http://kerneltrap.org/node/view/970 The bug was first submitted to Gentoo (http://bugs.gentoo.org/show_bug.cgi?id=67597) but they indicate it belongs upstream. Steps to reproduce: 1. in make menuconfig hit Y on File Systems -> Partition Types -> Advanced Partition Selection and Advanced Partition Selection -> Windows Logical Disk Manager (Dynamic Disk) support (NEW) 2. Select AMD-Opteron/Athlon64 under Processor type and features -> Processor family
