Hi Leo,
the messages in your syslog is written by the e1000 driver.
I compared the e1000 driver in SVN trunk with the one in 0.9.9.
One interesting difference is around line 316 in e1000_main.c.
In 0.9.9 it is
if ((err = rtdm_irq_request(&adapter->irq_handle, adapter->pdev->irq,
e1000_intr, RTDM_IRQTYPE_SHARED,
netdev->name, netdev)))
In trunk it is
if ((err = rtdm_irq_request(&adapter->irq_handle, adapter->pdev->irq,
e1000_intr, flags, netdev->name, netdev)))
If you have MSI enabled and if you have the PCIe e1000, the flags should be
zero.
Could you try to set flags to RTDM_IRQTYPE_SHARED in any case before calling
rtdm_irq_request?
I have no idea if this helps, but perhaps it is worth a try...
Regards
Mathias
