Unable to boot into 2.8.rc0

Hi, I downloaded the 2.8 iso and went about installing it. Everything went through fine including configuring the 3.4.7 kernel (didn't give any error). I even copied bzImage to boot along with System.map. However on trying to boot into Crux i got kernel panic saying "VFS: Unable to mount root, couldn't find valid ramdisk image", can't remember the exact error message but it should be quite similar to what i mentioned here. Can you please tell what could have gone wrong? There was a 3.4.7 patch file, i didnt do anything with that, could that be the reason or did i miss something else? The fact i didn't get any error during install but the OS not booting is bothering me a lot. Can someone please help? Thanks.

must be missing some drivers in the kernel configuration. filesystem drivers or IDE drivers, etc. Check on #crux on freenode. there are some very knowledgeable folks on it. On Sun, Aug 12, 2012 at 5:31 PM, Murali Bharadwaj <murali_sb2000@yahoo.com> wrote:

You probably forgot something in the kernel config. Make sure you enable everything you need to mount the root fs (and not as modules, catch 22) What has changed since the kernel included on the 2.7 iso is the need for: CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y It's required by the udev version that is shipped on rc0. Other common "gotchas" are SCSI-disk support, filesystem and your ide/sata/scsi controller. Remember that these devices must be built into the kernel (not as modules) unless you run a initrd. If you still have problems, please post your kernel config so we can have a look at it. -- Fredrik Rinnestam

Ok thanks for the prompt reply. Yes i was searching online when i saw some help related to what you've suggested. So i'm going to try one more time and enable everything this time ( i did last time as well but i could be wrong ). Will post kernel config if it fails again. regards, murali. ________________________________ From: Fredrik Rinnestam <fredrik@rinnestam.se> To: crux@lists.crux.nu Sent: Sunday, August 12, 2012 5:40 PM Subject: Re: Unable to boot into 2.8.rc0 On Sun, Aug 12, 2012 at 02:31:23PM -0700, Murali Bharadwaj wrote:

Hi, I was able to get past the kernel panic error that i was getting earlier. However this time when i rebooted into Crux for the first time after installation I got the error saying "root filesystem: no such file or directory" and it booted me into a maintenance mode asking me to change read-only file system to rw. I did that and it rebooted itself but gave the same errors again. Basically I was getting the same errors as listed in this url - https://bbs.archlinux.org/viewtopic.php?id=117733 As per one user who was able to get around the issue by downgrading udev I couldn't do that myself, as i was still in maintenance mode in read-only fs. Any help/suggestions greatly appreciated. thanks, murali.
