Distribution: Debian SID Hardware Environment: Intel PIII 800 Mhz, with 2 IDE disks. One disk (hda) has installed ontrack disk manager from Seagate because my latest bios version doesn't support disk sizes > 32 GB. Software Environment: Problem Description: At same distribution, using kernel 2.4.22 there was no problem with it, and hda has every of his partitions. My root is at /dev/hdb2, /dev/hdb3 is a swap, and my /home partition is at /dev/hda5, with other swap on /dev/hda3. When I tried to upgrade to 2.6.0, no partition in /dev/hda is seen as with 2.4.x: with older kernel, i have 5 partitions, and with 2.6 only one partition that seems to be dm6 and it's size is disk's size. fdisk sais that /dev/hda1 is of type 54, OntrackDM6. Restarting with 2.4.x the filesystems still are there and with it it's information. With hda=remap as a boot parameter I only get a disk with a bad partition table, as fdisk sais. As I haven't found information about this problem with linux, I think it would be a bug. Steps to reproduce: Install Ontrack Disk Manager DDO in a hard disk. Boot with kernel 2.6.0 That's all.
Try hda=remap63.
Fine. No problem with remap63. Perhaps it's better place to ask it, but... Why this change in this new kernel version? Is there any benefit with this? Thanks a lot, bzolnier.
