Greg and Kay:
When I boot 2.6.22-rc3 plus gregkh-all-2.6.22-rc3.patch, with an FC6
system (which includes a no-doubt somewhat altered version of udev
095), I get the follow message:

This doesn't happen under vanilla 2.6.22-rc3.
Is this udev's fault or is it a problem in the kernel? If it is udev's
fault, is it fixed in more recent versions?

Maybe it's a bug in:
driver/block-device.patch
in Greg's tree. It converts blockdevs from raw kobjects to devices.
Is this reproducible? It always happens?
Are you using initramfs?
What's the setting for CONFIG_SYSFS_DEPRECATED?
Care to comment out the block patch in the series file in Greg's tree
and try if it works?
Thanks,
Kay

In fact the gregkh-all patch file I used was a few days old (I
downloaded it from a mirror on May 29) and it doesn't include the
block-device patch in the first place. Should I try the current
version?

Hmm, then I have no idea what patch in Greg's tree could cause this,
even the block conversion patch is unlikely to cause a failure in the
block io_context functions.

Sure, it would be great, if you can sync up to the latest version of
Greg's patches yes, just to make sure we are not trying to fix something
that doesn't fail anymore.
