@related: Memory

I think I have the same custom essays,

If I helps I have noticed this with a card reader device (usb=0bda:0111) with kernel :

Linux hostname 2.6.24-19-rt #1 SMP PREEMPT RT Wed Jun 18 16:35:41 UTC 2008 i686 GNU/Linux

But I noticed it works fine on another system (same hardware) but previous kernel :

Linux hostname 2.6.24-12-rt #1 SMP PREEMPT RT Thu Mar 13 00:49:29 UTC 2008 i686 GNU/Linux

I'll may give more details laters at :
