It's a DMA issue. The chip raised an irq to signal the error condition to the driver, thats why it is printed by the irq handler. Happened while streamimg mpeg data. Havn't looked at the code for years now, but IIRC the 0x800000 is the raw error code from some status register, pci_abort is the error bit in clear text, meaning some PCI DMA transfer was aborted. No idea why though ... cheers, Gerd - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
