Hi all, I just want note that lot of ASUS board have buggy BIOS. Especialy ACPI DSDT table. I need to make a custom kernel with a custom DSDT to use this board correctly. Without, ACPI is fully disable and board doesn't work well.
Look at http://acpi.sourceforge.net/index.html and http://acpi.sourceforge.net/dsdt/index.php for more information. Custom DSDT for ASUS A8N-VM CSM were at http://acpi.sourceforge.net/dsdt/view.php?manufacturer=ASUS&name=A8N-VM+CSM My kernel .config include the following two lines: CONFIG_ACPI_CUSTOM_DSDT=y CONFIG_ACPI_CUSTOM_DSDT_FILE="/usr/src/dsdt.c" Using this patched DSTD in my kernel, I have now ACPI activated and have IRQ routing working very well. Perhaps all DMA errors are related to buggy ACPI DSDT on this board? I hope this can help someone. Regards, David Le Mar 3 octobre 2006 11:25, A. P.
