Dmesg errors on a freshly installed system

[skgucek]

Hello all,

I decided to install Gentoo on an old netbook, after the previous Arch system got too bloated ... anyway, all is well; I finished the install part of the Handbook, unmasked ~, upgraded everything, switched to -pf kernel and I am currently running "emerge -e @world" to get a fast, stable base before proceeding to install X, openbox et al.

Despite running -pf kernel, I think my kernel configuration is pretty sane (I can post the .config if necessary), except some strange dmesg errors are displayed if I insert an USB stick or boot with one inserted:

[...] sd 4:0:0:0: [sdb] No Caching mode page found
[...] sd 4:0:0:0: [sdb] Assuming drive cache: write through

Is this normal? It gets logged under the error (err) level. I am afraid to mount the USB drive until you guys assure me this is normal or tell me if I mucked something up while configuring the kernel.

Thanks a lot!
-S

I decided to wgetpaste some files you might be interested:

N.B. systemd and BTRFS errors can be safely disregarded as they are apparently unresolved bugs in kernel/btrfs.
