That might have been the case at some point but now sys-fs/udev-164-r2 and sys-fs/udev-171-r1 both install the firmware-related stuff (rules and helper) even with USE=-extras andrea

Filesystem is mounted, file is readable... 1) build the driver as a module (firmware loading from disk does not work otherwise) 2) emerge linux-firmware, if you haven't already. 3) reboot and good luck :)

I thought it was, but having another look at dmesg, it looks like that's not the case. proxy linux # dmesg | grep eth0 [0.897559] r8169 :02:00.0: eth0: RTL8168d/8111d at 0xc936, 1c:6f:65:20:3f:c6, XID 083000c0 IRQ 41 [ 70.453673] r8169 :02:00.0: eth0: unable to load firmware patch rtl_nic/rtl8168d-2.fw (-2) [ 70.461027] r8169 :02:00.0: eth0: link down [ 70.461050] r8169 :02:00.0: eth0: link down [ 70.461444] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 72.851287] r8169 :02:00.0: eth0: link up [ 72.851846] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready proxy linux # dmesg | grep btrfs [1.647953] btrfs: use lzo compression [2.129807] VFS: Mounted root (btrfs filesystem) on device 0:13. > In other words, are you perhaps using a ramdisk? > > If you have this drives as a module, can you try removing it (rmmod > and then reloading it (modprobe )? > > If it isn't a module, can you rebuild your kernel to have the relevant > driver as a module? Its not a module - i'll make it one and see how that goes.

Filesystem is mounted, file is readable... Is the filesystem mounted when it tries to find the firmware? In other words, are you perhaps using a ramdisk? If you have this drives as a module, can you try removing it (rmmod and then reloading it (modprobe )? If it isn't a module, can you rebuild your kernel to have the relevant driver as a module? -- Joost
