Can not get gentoo-sources 2.6.20 to boot

Ah, that would explain why my hard disk shows up as /dev/sda. I'm on an unusual system, and the ATA drivers are only available in the new format.

For those of you having the issue with the 2.6.20 kernel - can you try setting your grub (and you may need to change your fstab too) to hda instead of sda? I think you might be having the same problem I am. I have tried everything I can think of - recompiled my kernel at least 10 times already with every recommendation people have given me and still no luck (see my other thread: https://forums.gentoo.org/viewtopic-t-563862-highlight-.html).

I accidentally discovered that I could access my hard drive through /dev/hda* when I was following the Gentoo Handbook and made a typo. "genkernel -all" doesn't even work for me with 2.6.20. Everything works flawlessly on /dev/sda* off the 2007.0 minimal install CD (which I believe runs 2.6.19).

Though /dev/hda works and allows me to boot A) it's just not right and B) I get awful disk performance (~1.5 MB/sec buffered disk reads with "hdparm -tT /dev/hda").

I'm off to try 2.6.21, but I'd be really curious to see anyone else's results with 2.6.20.

Thank you all! After weeks of troubleshooting I finally have my SATA drive recognized properly and working beautifully. It was this thread that prompted me to try a different kernel version - it turns out I do know how to config a kernel properly!

Is there someone official to notify of this sort of kernel bug?

cyrxi,

File a bug at bugs.gentoo.org However, if its already fixed in a later version thats likely to be your answer.
Do check that your bug will not be a duplicate of an existing bug.
The Gentoo devs will pass your bug to the kernel project if needed.

I haven't tried the 2.6.20 vanilla kernel, so I don't know if the problem would be in the gentoo patch or the incoming kernel source. I agree that filing a bug would mostly be for documentation purposes since it is fixed in later versions.

I'm getting exactly this bug in 2.6.22-r8... anyone else?

I also get the same error with 2.6.22-r8 version. I think the kernel doesn't know how to deal with the SCSI device. Any suggestions?
