Wow, this is horrible. This patch should help a bit. But it's probably hard to workaround that DMA issue completely. There still is a chance of corruption, as soon as the kernel allocates and uses some memory that the DMA controller still uses from boot-up before the fixup is applied. -- Michael -------------- next part -------------- A non-text attachment was scrubbed...
