The original report was made on 2.6.22-rc3, I just checked and it still 
happens on 2.6.22-rc5.

Can you use 'git bisect' to track down the patch that causes this to
fail?

thanks,

I will do this, however, it will likely take me a day or two to find. I'll 
report back then.

Well, more likely a few more days due to difficult physical access to the 
laptop at the moment; however, it's *not* a regression introduced in 
2.6.22rc, it was introduced at some point of time between 2.6.18 and 
2.6.19-rc1.

That means IMHO it's not sensible holding 2.6.22 final waiting for a fix for 
this issue, but I will try to hurry in locating the exact commit anyway.

Great, thanks for letting us know about this.
