I recently upgraded my uml-kernel.
My system is composed by: kernel 2.6.17-gentoo-r8-skas3-v9-pre9 #8 SMP PREEMPT Tue Sep 26 16:16:05 CEST 2006 x86_64 AMD Athlon(tm) 64 Processor 3000+ GNU/Linux
glibc-2.4-r3
Actually I use a well-working uml kernel (2.6.16.24).
I decided to upgrade my guest kernel to 2.6.18. Patches were applied as required (uml-2.6.18-bb1.patch.bz2 to guest and skas-2.6.17-rc5-v9-pre9.patch.bz2 to host kernel).
My boot problem is the following message:
Checking host MADV_REMOVE support...MADV_REMOVE failed, err = -22
