Good day,

I succesfully built a 2.6.39.4 with all the relevant xen support and booted my 
dom0 into this (previously this machine ran the RHEL5 kernel-xen with no 
glitches).

DomU machines get succesfully started as far as Xen is concerned (all devices 
connected, domain unpaused), but then I get the dreaded "XENBUS: Waiting for 
devices to initialise: 295s...290s...285s..." for both vbd's assigned to the 
guest.

After the timeouts, the guest goes into a kernel panic. Guest worked fine when 
dom0-kernel was 2.6.18 and nothing else was changed.

This is the output of xm block-list for the guest. I dont know what "state 3" 
means.

(51713
    ((virtual-device 51713)
        (device-type disk)
        (protocol x86_64-abi)
        (backend-id 0)
        (state 3)
        (backend /local/domain/0/backend/vbd/2/51713)
        (ring-ref 8)
        (event-channel 8)
    )
)
(51714
    ((virtual-device 51714)
        (device-type disk)
        (protocol x86_64-abi)
        (backend-id 0)
        (state 3)
        (backend /local/domain/0/backend/vbd/2/51714)
        (ring-ref 9)
        (event-channel 9)
    )
)

Am I missing something?

Cheers,
Pim
