Screenshot of kernel panic
Description of problem:
After yum upgrade to kernel-188.8.131.52-5.fc15.i686, the machine does not boot up any more (see attachment). Kernel kernel-184.108.40.206-0.fc15.i686 still works fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2. kernel panic
using the old kernel-220.127.116.11-0 is a workaround
Can you get more of the kernel boot logs? It can't find the rootfs with that kernel, which might be due to the initramfs being corrupted or missing, or it might be something else.
To check the initramfs, make sure there is an initramfs file that matches the version number in /boot and is of similar size as the others. Then make sure the bootloader config lists an initrd line with that initramfs file.
initramfs wass mising for that kernel version. I removed the kernel and reinstalled it, and everything is fine now.
It seems that initramfs was not created during the first installation?
Thanks for letting us know. You'd need to look in your yum update logs and see if there was an error in producing the initramfs.
It seems that "yum update" got interrupted *after* installing the new kernel, but *before* creating initramfs. yum-complete-transaction didn't recognized the incomplete kernel installation.
