Just found the same input/output error on 18.04 with Linux version 5.0.0-25-generic:
$ lspci -vv -s 08:00.0 08:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c) ... pcilib: sysfs_read_vpd: read failed: Input/output error ... It seams it happens, when the /sys/bus/pci/devices/0000:08:00.0/vpd is accessed: $ strace -o /tmp/strace.log lspci -vv -s 08:00.0 > /dev/null pcilib: sysfs_read_vpd: read failed: Input/output error $ cat /tmp/strace.log | grep -B 2 -C 2 "Input/output error" pread64(3, "\3\0\0\0", 4, 208) = 4 openat(AT_FDCWD, "/sys/bus/pci/devices/0000:08:00.0/vpd", O_RDONLY) = 5 pread64(5, 0x7fff8ed80e2e, 1, 0) = -1 EIO (Input/output error) write(2, "pcilib: ", 8) = 8 write(2, "sysfs_read_vpd: read failed: Inp"..., 47) = 47 It can be reproduced by reading the device directly: $ cat /sys/bus/pci/devices/0000:08:00.0/vpd cat: '/sys/bus/pci/devices/0000:08:00.0/vpd': Input/output error It seams that this is a kernel issue, because the vpd is created, even if the device (in my case the RTL8111/8168/8411) does not support vpd.
