Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.12 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi,

 This also seems to be present on 16.04.

Linux qfsd-4 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 18:08:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

[Luke Mulkey (lwmulkey)]

See the same failure on kernel 4.13 but NOT on 4.4

[Simon Sudler (simonsudler)]

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.

There is also a kernel bug report: https://bugzilla.kernel.org/show_bug.cgi?id=199467

[Kai-Heng Feng (kaihengfeng)]

Please test latest mainline kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc4/

[Simon Sudler (simonsudler)]

Yes, issue is also in v5.3-rc4.
