Diese Meldung z.B. ist nach dem Update auf Linux Kernel v4.6.5 nicht mehr vorhanden: [ 4.383178] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 49 [ 4.383258] Raw EDID: [ 4.383323] 00 ff ff ff ff ff ff 00 15 c3 88 16 01 01 01 01 [ 4.383394] 24 0d 01 02 68 26 1e 78 ea e1 ff ff ff ff ff ff [ 4.383466] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 4.383537] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 4.383608] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 4.383680] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 4.383751] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 4.383822] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ===== Ausgabe von lspci aktualisieren ===== ''lspci'' ist ein sehr wertvolles Werkzeug. Ab und zu sind die Ausgaben aber nicht ganz stimmig mit den Meldungen aus z.B. ''dmesg''. Dafür gibt es in Debian das kleine Hilfswerkzeug ''update-pciids'' was ''lspci'' mit frischen Informationen versorgt. Gerade die Information zu den 10 GbE Schnittstellen auf diesem Supermicro Board ist wesentlich informativer: **Intel Corporation Device 15ac** vs. **Intel Corporation Ethernet Connection X552 10 GbE SFP+** **Vorher** 00:00.0 Host bridge: Intel Corporation Broadwell DMI2 (rev 03) 00:01.0 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 1 (rev 03) 00:01.1 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 1 (rev 03) 00:02.0 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 2 (rev 03) 00:02.2 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 2 (rev 03) 00:03.0 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 3 (rev 03) 00:03.2 PCI bridge: Intel Corporation Broadwell PCI Express Root Port 3 (rev 03) 00:05.0 System peripheral: Intel Corporation Broadwell Adress Map/VTd_Misc/System Management (rev 03) 00:05.1 System peripheral: Intel Corporation Broadwell IIO Hot Plug (rev 03) 00:05.2 System peripheral: Intel Corporation Broadwell IIO RAS/Control Status/Global Errors (rev 03) 00:05.4 PIC: Intel Corporation Broadwell I/O APIC (rev 03) 00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 05) 00:16.0 Communication controller: Intel Corporation 8 Series/C220 Series Chipset Family MEI Controller #1 (rev 04) 00:16.1 Communication controller: Intel Corporation 8 Series/C220 Series Chipset Family MEI Controller #2 (rev 04) 00:1a.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #2 (rev 05) 00:1c.0 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #1 (rev d5) 00:1c.1 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #2 (rev d5) 00:1c.3 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #4 (rev d5) 00:1c.4 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #5 (rev d5) 00:1d.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation C224 Series Chipset Family Server Standard SKU LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 8 Series/C220 Series Chipset Family 6-port SATA Controller 1 [AHCI mode] (rev 05) 00:1f.3 SMBus: Intel Corporation 8 Series/C220 Series Chipset Family SMBus Controller (rev 05) 00:1f.6 Signal processing controller: Intel Corporation 8 Series Chipset Family Thermal Management Controller (rev 05) 01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd Device a802 (rev 01) 03:00.0 System peripheral: Intel Corporation Device 6f50 03:00.1 System peripheral: Intel Corporation Device 6f51 03:00.2 System peripheral: Intel Corporation Device 6f52 03:00.3 System peripheral: Intel Corporation Device 6f53 04:00.0 Ethernet controller: Intel Corporation Device 15ac 04:00.1 Ethernet controller: Intel Corporation Device 15ac 08:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) 09:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) 0a:00.0 PCI bridge: ASPEED Technology, Inc.
