eSATA ExpressCard not recognized

Hello all,

I have a Dawicontrol DC-300 eCard with a Siliconimage chip. When i hotplug the card into my laptop it does not get recognized by the system. There is not even an entry in the output of dmesg. When i do a reboot the card gets recognized correctly and the module "sata_sil24" has been loaded. My system is Fedora 14 64 bit.
What can i do to make hotplugging of the eCard work?

Thanky you and best regards,
pukpuk

try doing a "modprobe pciehp" (as root) and then try to hotplug your card and see if it works.

However, some of the hotplug support was incompatible with suspend at one time. I'm not sure if this has been fixed or not.

Unfortunately it doesn't work. It's builtin and not a module anymore.

Re: eSATA ExpressCard not recognized

grrr. I forgot they compiled it into the kernel now..

try this instead.

as root, edit your /boot/grub/grub.conf file
at the end of the kernel line append this:

Code:
pciehp.pciehp_force=1
I don't think you have to run dracut to create a new initramfs for this, but if you do:

Code:
cp /boot/initramfs-$(uname -r).img initramfs-$(uname -r).bak
dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

not sure, but I think that the hotplug messed up suspend on some systems, so they went with what mesed up the least number of systems. took away hotplug and kept suspend.
