Syslog spammed by 10 lines every 2 seconds

[gpothier]

This is a followup to bug #1390182, which is marked as fixed. Although the situation has improved a lot, I still get 10 useless lines in syslog every 2 seconds:

[Brad Figg (brad-figg)]

This change was made by a bot.

[Chris J Arges (arges)]

So this is a different bug since this message originates somewhere else.

The two messages are:

pci_bus 0000:09: Allocating resources
i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

Looking at upstream I don't see any patches that seem to change those two messages, and 'Allocating resources' should be a DEBUG message; while 'has bogus alignment' is WARN.

Have you altered your kernel log settings at all?

Another approach would be to test latest mainline to see if there were other fixes that would cause these messages to not be triggered. If you are able to test, can you install mainline and see if those messages persist?

[gpothier (gpothier)]

I don't think I have altered my kernel log settings. Here is what I have:
gpothier@tadzim2:~$ cat /proc/sys/kernel/printk
4 4 1 7

gpothier@tadzim2:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.18.0-999-generic root=UUID=b26f4d55-88e9-4a68-8456-8a7260aa20a9 ro quiet splash vt.handoff=7

I tried mainline kernel, the same messages are printed.

[gpothier (gpothier)]

Probably just stating the obvious here, but if the "bogus alignment" is a warning message, then maybe it shouldn't be silenced, but rather the underlying issue looked at?
