Notebook: Asus X51R
OS: Ubuntu 9.04
Kernel: 2.6.31 (2.6.30)

SD-card worked fine with original 2.6.28 kernel (Ubuntu 9.04). But with new kernels 2.6.31 and 2.6.30 (mainline kernel from https://wiki.ubuntu.com/KernelTeam/MainlineBuilds) I have this problem:

  1. Inserting SD-card. All work fine: Ubuntu sees this card.
  2. Removing SD-card.
  3. Inserting SD-card again. Ubuntu DOES'T see this card.
  4. Removing SD-card.
  5. Rebooting the system. GOTO 1

I suppose that this problem will appear in new Ubuntu 9.10.
