If you burn data in DAO mode you will have the same behaviour. Have you tried to toggle CONFIG_IDEPCI_SHARE_IRQ? It helped me a lot. Also I have to disable umaskirq, otherwise I have the same problems. Unfortunately I can't use the latest ac series because of a mysterious problem with ide-scsi. One thing I still do not understand is: IS DMA (theoretically) possible for stuff like c2scans, DAO writing, audio grabbing? From what I read in the LKML archives and from what Andre wrote me, I'd say no, but on the other hand I can do a c2scan at 5MB/s with almost no processor usage. Can't really be PIO. regards Markus - 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/ | ||||||||||||
