Does someone know if AMD and Nvidia is still investigating? 2) Steve Langasek from Debian sent me a patch that disables the hw-iommu per default on Nvidia boards. I've attached it in the kernel bugzilla and asked for inclusion in the kernel (until we find a real solution). I'd be pleased if all of you (who experienced the data corruption) could test this patch. Note: This patch is NOT a real solution for the issue, it just applies our workaround (iommu=soft) per default Bugreport at kernel.org: http://bugzilla.kernel.org/show_bug.cgi?id=7768 Bugreport at Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=404148 Best wishes, Chris. --------------050404080601070802050702 Content-Type: text/x-vcard; charset=utf-8; name="calestyo.vcf" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="calestyo.vcf" YmVnaW46dmNhcmQNCmZuOk1pdHRlcmVyLCBDaHJpc3RvcGggQW50b24NCm46TWl0dGVyZXI7 Q2hyaXN0b3BoIEFudG9uDQplbWFpbDtpbnRlcm5ldDpjYWxlc3R5b0BzY2llbnRpYS5uZXQN CngtbW96aWxsYS1odG1sOlRSVUUNCnZlcnNpb246Mi4xDQplbmQ6dmNhcmQNCg0K --------------050404080601070802050702--
