Hi, I'm having an issue with my Thinkpad P70 laptop/workstation. This system is a dual boot, windows 10 pro and centos 7. I have not needed to use the cdrom until now, however the system does not see it in /dev. I know the cdrom works as I can use it in windows 10 and when initially installing centos 7, I installed from dvd media. I'm not sure what to check. I do not see anything related in dmesg. I have previous copies of kernel on the system and tried booting with 3.10.0-957.el7.x86_64 but I'm seeing the same. ---------- # uname -r 3.10.0-957.21.3.el7.x86_64 # lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics P530 (rev 06) 00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation 100 Series/C230 Series Chipset Family Thermal Subsystem (rev 31) 00:16.0 Communication controller: Intel Corporation 100 Series/C230 Series Chipset Family MEI Controller #1 (rev 31) 00:16.3 Serial controller: Intel Corporation 100 Series/C230 Series Chipset Family KT Redirection (rev 31) 00:17.0 RAID bus controller: Intel Corporation SATA Controller [RAID mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #1 (rev f1) 00:1c.2 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #3 (rev f1) 00:1c.4 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #5 (rev f1) 00:1d.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #13 (rev f1) 00:1f.0 ISA bridge: Intel Corporation CM236 Chipset LPC/eSPI Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation 100 Series/C230 Series Chipset Family Power Management Controller (rev 31) 00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31) 00:1f.4 SMBus: Intel Corporation 100 Series/C230 Series Chipset Family SMBus (rev 31) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM (rev 31) 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M600M] (rev a2) 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) 05:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:01.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:02.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:04.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 07:00.0 System peripheral: Intel Corporation DSL6540 Thunderbolt 3 NHI [Alpine Ridge 4C 2015] (rev ff) 3b:00.0 USB controller: Intel Corporation DSL6540 USB 3.1 Controller [Alpine Ridge] 70:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Why not use 'hwinfo --cdrom'? # hwinfo --cdrom --short cdrom: /dev/sr0 TSSTcorp DVD+-RW TS-H653H P.
