kernel: pcie_portdrv_probe->Dev[005d:10de] has invalid IRQ. Check vendor

BIOS

These messages indicate that certain PCI-E ports are not requesting IRQs. They do not, however,

affect the operation of the machine in any way.

• Removable storage devices (such as CDs and DVDs) do not automatically mount when you are

logged in as root. As such, you will need to manually mount the device through the graphical file

manager.

Alternatively, you can run the following command to mount a device to /media:

mount /dev/[device name] /media

• When a LUN is deleted on a configured storage system, the change is not reflected on the host. In

such cases, lvm commands will hang indefinitely when dm-multipath is used, as the LUN has

now become stale.

To work around this, delete all device and mpath link entries in /etc/lvm/.cache specific to the

stale LUN.

To find out what these entries are, run the following command:

ls -l /dev/mpath | grep [stale LUN]

For example, if [stale LUN] is 3600d0230003414f30000203a7bc41a00, the following results may

appear:

lrwxrwxrwx 1 root root 7 Aug 2 10:33 /3600d0230003414f30000203a7bc41a00

-> ../dm-4

lrwxrwxrwx 1 root root 7 Aug 2

10:33 /3600d0230003414f30000203a7bc41a00p1 -> ../dm-5

This means that 3600d0230003414f30000203a7bc41a00 is mapped to two mpath links: dm-4 and

dm-5.

As such, the following lines should be deleted from /etc/lvm/.cache:

/dev/dm-4

/dev/dm-5

/dev/mapper/3600d0230003414f30000203a7bc41a00

/dev/mapper/3600d0230003414f30000203a7bc41a00p1

/dev/mpath/3600d0230003414f30000203a7bc41a00

/dev/mpath/3600d0230003414f30000203a7bc41a00p1

• Running the multipath command with the -ll option can cause the command to hang if one of

the paths is on a blocking device. Note that the driver does not fail a request after some time if the

device does not respond.
