I''m having problems starting more than three domains. It sometimes works fine, but more often than not the 4th domain''s root block device times out and so the domU kernel panics as there''s no /dev/root: XENBUS: Timeout connecting to device: device/vbd/2057 (state 6) XENBUS: Timeout connecting to device: device/vif/0 (state 6) XENBUS: Timeout connecting to device:

While writing a driver for a device doing lots of DMA I''ve hit an "swiotlb_full()" problem. This surprised me somewhat as I wouldn''t have expected to need the use of the software TLB - it''s a 64 bit capable device on a server with only 2 GB of RAM, and so I''d have expected to be using a hardware TLB. Is this a peculiarity of Xen, or should I be right

...ctly what - I''ve not managed to reproduce it myself) seems to try to flush the workqueue, and so it deadlocks. This patch fixes the problem by giving the accel watch work item its own workqueue, and so modprobe can successfully flush the system-wide one.
