lvm and kernel 2.6

[Benoit <benoit.peccatte@enst-bretagne.fr>]

Hello,

I'm currently using debian unstable with a 2.6-test9 kernel from debian 
source, some of my partitions are lvm. It worked great until my last upgrade 
(yesterday was the first one after the come back of the ftp server). 

I now get an error on vgscan : ioctl, invalid argument cmd(0)
It still works under a 2.4 kernel, but I'm unable to get anything under the 
2.6

Any idea on the problem ?

Thank you,
Benoit.
