Hello again
Ive tried some advices you gave me, use hda=remap at boottime, puting this options CONFIG_PARTITIO_ADVANCED=y and CONFIG_LDM_PARTITION=y, taking out initrd suport. But I havnt had any improovment. But I am starting to thing it is about how my HD is managed. I have a SEGATE 20Gb drive. My BIOS does not recognize that amount of disk, so I use a program that is on MBR provided by Segate that makes the 20Gb abiavle. In kernel 2.4 it works just fine, but maybe that is the cause 2.6 can not boot... am I right? what else could I try?

GIVEUP [bootup kernel panic 2.6.x] no root partition detected?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello again, after two days of trying to solve my problem I give up now. I tried lots of diferent configurations, so I do not know if it is a kernel BUG or what, because Ive seen similar threads in this mail-list and in other lists, irc chats...
I definitevily giveup of trying use 2.6.x in that computer, if someone wants to investigate what happened and need config files, logs or whatever, just tell me...
I am sure it is a kernel-hardware interactuation problem, because there is no configuration I can do for this to work... so... giveup...

Thanks anyway to all of you that took the time of reading this mail...

Re: GIVEUP [bootup kernel panic 2.6.x] no root partition detected?

Thanks for your answer, I use LILO but that root is refering to presisely the root partition, in my case it its /dev/hda5... It is well configured in lilo, I can enter with kernel 2.4... but not with 2.6...
if you want to know, the exact Kernel error at the begining is:

VFS: Cannot open root device "305" or hda5
Please append a correct "root=" boot option

Kernel panic: VFS: Unable to mount root fs on hda5

but I know hda5 is the partition, maybe there has something to be with the fact that the root partition is logical, in the extended partiton... I mean is not a primary partition... could this be true???

Thats an excellent question, unforch I don't know the definitive answer. But to put that fear to rest, my / partition is on /dev/hda7, and /root is on /dev/hda5. I would think that if thats a problem, I would have seen it, and I've been setup that way for the last 6 months or so.

That really shouldn't make any more difference than putting /usr on a seperate drive does, which is no diff, at least here.

Sorry Pablo, but I'm fresh out of ideas. But there may be enough clues here that someone else can chime in.

Hello again, after two days of trying to solve my problem I give up now.

Hmm - no information at all?

Let me search the archives.

Partition check:
hda: [DM6:DD0] [remap +63] [2480/255/63] hda1 hda2 <hda5 hda6 hda7 hda8 hda9 hda10 hda11 hda12>

Aha. Boot, and give boot parameter "hda=remap63".

Nevertheless that was the right answer.
(Or at least part of the right answer.)
