I think I've understood correctly. IIRC, if you use 2.6 as host (even
2.6-test), an UML bug appears. That bug is not triggered if you have a 2.4
host; also, it appears randomically (not with /bin/sh, not with the Debian
rootfs but could reappear even with them...). The patch has been applied to
later 2.4 guest, not to stock 2.6 guest; see the end of this email to find

It is a kernel option or patch on the host kernel. I can guess that having
2G/2G is needed if you have at least 900 Mega of Ram on the host.

I have no idea about this. Maybe, you enabled an option on the kernel compile
and didn't enable it now.
Since you didn't apply a 2G/2G patch, I guess you've set CONFIG_HIGHMEM.

The host normally doesn't compile with SKAS if you don't enable /proc/mm.
Also, I don't think you have applied SKAS for 2.6.
If you need any UML patch for 2.6, I think you should go here:
There you'll find SKAS for the host, a fix for the bug above(the G-02... one),
fix for modules + other stuff. See instructions you find in that page and in
the Readme, and note the warning about the A-04 patch.
