I did the suggested testing now and everything still behaves like the
2.6.30-distro kernel from Debian. Cool work!

This also means, I discovered something I never noticed before. This happens
when I remove CF-cards (same for both types I have lying here):

[  150.313371] pcmcia_socket pcmcia_socket0: pccard: PCMCIA card inserted into slot 0
[  150.314593] pcmcia 0.0: pcmcia: registering new device pcmcia0.0

[  151.327094] ide-cs: hde: Vpp = 0.0
[  154.778843] pcmcia_socket pcmcia_socket0: pccard: card ejected from slot 0
[  154.779280] Trying to free nonexistent resource <000000000000c10e-000000000000c10e>
[  154.779289] Trying to free nonexistent resource <000000000000c100-000000000000c107>

The last two lines sound like a problem. Is it known? (I repeat: This is not a
regression of your patches, it also happens with 2.6.30.)

Regards,
