[Bug 313487] Re: RAID1 array affected by non-RAID swappable IDE disk

[Axel Müller]

Ok - Because I would like to see this bug fixed I restarted my server
today (after 6 month uptime) in order to boot the latest official
kernel:

Linux gate 2.6.24-27-server #1 SMP Mon Feb 22 19:42:25 UTC 2010 i686
GNU/Linux

Exactly as one year ago this kernel has the same problem:

At the moment my RAID is rebuilding. 
Next weekend I should give Lucid and/or the latest upstream kernels a try.
