Description Jarkko 2007-02-19 01:08:03 UTC

Description of problem: dmraid stopped from working after kernel upgrade. Worked
with Fedora 7 Test1 kernel. 

Version-Release number of selected component (if applicable):
kernel-2.6.20-1.2932.fc7

How reproducible: Always (done twise).

Steps to Reproduce:
1. get Fedora 7 Test1 CD
2. install using dmraid
3. yum upgrade kernel + reboot
  
Actual results: /dev/mapper/ does not contain the raid devices anymore.

Expected results: /dev/mapper/ should continue to contain the raid devices.

Additional info: I _only_ updated the kernel package, so I am 100% sure that
"yum upgrade kernel" broke this.

- Working kernel: kernel-2.6.19-1.2914.fc7

I extracted the initrd images and compared them. The cause for this problem has
been found:
