Dell Inspiron 5150 PCMCIA troubles

[Alex Buell]

Hi,

I'd like to report a problem with my Dell Inspirion 5150. Inserting a
PCMCIA cardbus card causes a freeze, everything just locks up solidly.
Ejecting the card causes a spontaneous reboot. I am running Gentoo
Linux on this laptop, release 2.6.25-gentoo-r7. Here's my dmesg output
pertaining to the cardbus:

Yenta: CardBus bridge found at 0000:02:04.0 [1028:015f]
Yenta: Using CSCINT to route CSC interrupts to PCI
Yenta: Routing CardBus interrupts to PCI

lspci -v output:

	Kernel driver in use: yenta_cardbus
	Kernel modules: yenta_socket

Looking at the logs after the reboot, there isn't anything amiss that
I could find. I am also using pcmciautils release 014.

Suspecting a hardware problem, I downloaded and booted Dell
Diagnostics and ran a test on the PCMCIA hardware. I even inserted and
ejected a Cardbus card quite a few times during the diagnostics, no
freezes or reboots occurred, and the diagnostics was perfectly aware
that a card had been inserted or ejected. 

Any ideas? I would be quite happy to try things out, see if I can get
this working. 

Thanks
