User-Agent: Mutt/1.5.9i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi! I see some problems in pcmcia subsystem in 2.6.12-rc4: On compaq nx5000, inserting CF ide card is recognized as anonymous memory. On compaq evo, it is recognized okay and mounts/works. Unfortunately when I unplug the card, I get an oops: Message from syslogd@Elf at Wed May 25 13:25:25 2005 ... Elf kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000010 Message from syslogd@Elf at Wed May 25 13:25:25 2005 ... Elf kernel: printing eip: Message from syslogd@Elf at Wed May 25 13:25:25 2005 ... Elf kernel: *pde = 00000000 Message from syslogd@Elf at Wed May 25 13:25:25 2005 ... Elf kernel: Oops: 0000 [#1] . -mm kernel actually works better on nx5000; it behaves similary to -rc4 on evo; unfortunately it produces similar oops on card unplug. Pavel
