dmraid stopped from working after kernel upgrade
Last modified: 2007-11-30 17:11:57 EST
Description of problem: dmraid stopped from working after kernel upgrade. Worked
with Fedora 7 Test1 kernel.
Version-Release number of selected component (if applicable):
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
- Same issue happens also with: kernel-xen-2.6.19-1.2898.2.3.fc7 (see bug #229161)
The currently latest kernel-2.6.20-1.2936.fc7 doesn't work either.
The currently latest kernel-2.6.20-1.2940.fc7 doesn't work either.
The currently latest kernel-2.6.20-1.2942.fc7 doesn't work either.
I extracted the initrd images and compared them. The cause for this problem has
