This is probably related to inclusion of sun disklabel in kernel (I haven't checked this but it looks like it is included). Have a look at partition table: /dev/sda1 1 255 2048256 83 Linux /dev/sda2 * 256 509 2040255 82 Linux swap /dev/sda3 510 1106 4795402+ 5 Extended /dev/sda5 510 526 136521 82 Linux swap /dev/sda6 527 532 48163+ 83 Linux /dev/sda7 533 915 3076416 83 Linux /dev/sda8 916 1106 1534176 83 Linux sda2 is Solaris 7 on x86. After installation (which for some reason hasn't finished - it stalled after upgrading all packages) new kernel refused to load saying it can't mount root. Adding 4 to all partitions after sda5 in fstab and lilo.conf helped. But still fdisk shows the same picture as above which is inconsistent with kernel knowledge about partition table and current mountpoints. I have a feeling that lilo doesn't handle this situation well as well - I had to use rescue mode to change boot record on sda6 (picture above). sda is second disk on this system (first one is ide on hda). Please note that including sun disklabel may need some added code during installation (at least for upgrade option which seems to rely on existing fstab) and may require it to be included in kernel used during install (which I believe is not a case). I used smp kernel.
This is showing up with the UnixWare support as well. We normally install Linux on the 4th physical partition in an extended partition that is beyond the 1023-cylinder boot limit. Our first partition on the systems is normally a UnixWare 7 partition. Because UnixWare support is now compiled into the default Red Hat 6.2 kernel, the system is now seeing hda1 <Unixware hda5 hda6 hda7 hda8 hda9 hda 10> hda2 hda3 <hda11 hda12> on boot, but during the install process is seeing hda1 hda2 hda3 <hda5 hda6>. A temporary fix is to boot with the Linux install floppy and change the partition type number for the Unixware partition to a DOS-type number (using fdisk). When we do this, however, Unixware will Kernel Panic on bootup because it cannnot locate it's root filesystem. Manually changing the boot device in lilo.conf on the boot floppy to hda11 does not solve the problem.
(after talking with my boss): I need to say this about myself: I am a contractor for Intel Corporation, not an employee, and as such, my opinions are no reflection of the views or conerns of the Intel Corporation.

Having 2 different sets of extended partitions isn't support by many linux tools, and confuses many operating systems horrible. Don't do that.
