So this is a regression, but not from 2.6.24 (although somehow it never hit me before). I don't know about the policy of closing regressions that come from way before the previous kernel version, if there is any. Then I will let you manage the bugzilla #10117 as you see fit (but I will be "there" to hopefuly test any proposed patches). Thanks, Carlos
