I tried today''s unstable on some IBM hardware and get this IRQ message
at boot when xenU tries to probe the virtual block device:
Xen virtual console successfully installed as tty1
Event-channel device installed.
xen_blk: Initialising virtual block device driver
Trying to free free IRQ261
vbd: probe of vbd-769 failed with error -2
xen_blk: bind_evtchn_to_irqhandler failed (err=-16)
vbd: probe of vbd-770 failed with error -2
XENBUS xs_read_watch: 0
xen_blk: Timeout connecting to device!
xen_net: Initialising virtual ethernet driver.
vif: probe of vif-0 failed with error -2
XENBUS xs_read_watch: 0
xen_net: Timeout connecting to device!
The same linux-2.6 xen0/xenU kernels work fine on a scsi DELL PE1650. The same
''free free IRQ'' message happens on IBM x335 (scsi and IDE) and
HS20 (IDE).
The message is from free_irq() in linux-2.6-xen-sparse/kernel/irq/manage.c:
printk(KERN_ERR "Trying to free free IRQ%d\n",irq);
xen-2.0.5 works fine on all these hosts.
I tried building a linux-2.4 xenU from the unstable pull
to see if it would boot, but make failed with this message:
xen/xen-unstable.hg/linux-2.4.30-xenU/include/asm/evtchn.h:55: error:

xen/xen-unstable.hg/linux-2.4.30-xenU/include/asm/irq.h:44: error: previous

xen/xen-unstable.hg/linux-2.4.30-xenU/include/asm/evtchn.h:56: error:
