Just on the off chance... When the host starts UML, you do
export LD_ASSUME_KERNEL=2.4.1
right? (2.4.1 per BlaisorBlade; but in SuSE 9.2 with glibc-2.3.3, 2.4.21
is used by a SuSE script and seems to be sufficient.)
It's an issue with thread local storage, and UML can't deal with the most
recent incarnation, either on the host or within the guest, because it has
no access to the underlying hardware, so you lie about the kernel version
to make it use the older style. This caused me no end of trouble until I
received the advice to set this environment variable both when starting
UML on the host and when executing on the guest.
