prism54: request_firmware() failed for 'isl3890'
eth0: could not upload firmware('isl3890')
Ich hab das einfach überprüft durch: "cat .config | grep OPTION". Wobei Option für die oben genannten Kerneloptionen steht, also einfach ersetzen.* Kernel requirements:
-----------------------------------------------------------
v2.6:
CONFIG_EXPERIMENTAL: y
CONFIG_CLEAN_COMPILE: n
CONFIG_STANDALONE: n
Code maturity level options --->
Prompt for development and/or incomplete code/drivers
Select only drivers expected to compile cleanly
Select only drivers that don't need
compile-time external firmware
CONFIG_HOTPLUG : y
Bus options (PCI, PCMCIA, EISA, MCA, ISA) --->
Support for hot-pluggable devices
CONFIG_FW_LOADER: m/y (either one will work)
Generic Driver Options --->
Hotplug firmware loading support
CONFIG_NET_RADIO : y
CONFIG_NET_WIRELESS : y
Device Drivers --->
Networking Support --->
Wireless Lan drivers
For PCMCIA Cards :
CONFIG_PCMCIA && CONFIG_CARDBUS
Bus options (PCI, PCMCIA, EISA, MCA, ISA) --->
PCMCIA/CardBus support --->
PCMCIA/CardBus support (m or y)
CardBus yenta-compatible bridge support (m or y)
You need sysfs mounted:
mkdir /sys
Add "none /sys sysfs defaults 0 0" to /etc/fstab
mount /sys
-----------------------------------------------------------
Firmware/hotplug
----------------
This driver needs to upload the firmware to the NIC's ram on initialization
it does so by requesting the firmware from the hotplug subsystem by asking
for "isl3890" or "isl3877" depending on the hardware detected. We don't
actually know of any card using isl3877 so if you do let us know
Make sure the hotplug system has been setup properly, otherwise you
might get errors in the kernel log stating that request_firmware() has failed
*) does "cat /proc/sys/kernel/hotplug" show something like "/sbin/hotplug"?
*) is /sbin/hotplug present?
*) is the "firmware" agent is present (call /sbin/hotplug without
any argument to show a list of available agents)
*) have you copied the firmware file into the folder expected by
firmware.agent? (usually "/usr/lib/hotplug/firmware/")
*) for 2.6.x you need to mount sysfs!
Other issues not directly related to firmware uploading:
*) [cardbus] have 'yenta_socket' module loaded in order to make cardbus
card visible to the kernel pci subsystem? (check with lspci(1) whether
device is visible to the kernel)
