I have found that a proper reboot is impossible once the card/driver starts misbehaving. Anything that tries to do anything with the md device, or any of the component drives will hang. Even kernel threads it seems. A reboot or a shutdown hangs when it tries to sync the md device, and ALT+SYSRQ+S/U both hang. After the first Alt+sysrq+s it will register more of them, but it won't print the "Emergency Sync Complete" message. > Does anyone have a working config based on a Marvell 64xx card ? > > I'm willing to explore solutions, patches or anything, just tell me what > to do to help. > > Christian Vilhelm. > -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
