I am using the 3.19.0-031900 kernel with Ubuntu 14.04 and I am seeing
the 'Magrathea' message in dmesg:
$ dmesg -T|grep -E "(319|Magra)"

Awesome, thanks for testing. The kernel currently in -proposed is
3.18.0-14.15 and it's likely the last 3.18 kernel for Vivid -- the next
one should already be a 3.19 kernel. Since 3.19 kernel already contains
the fix for this bug, I don't think there's a need to actually SRU the

After 24 hours of use, still no slub.c error message in dmesg.
$ dmesg | grep -i slub

After the autoremove & purge, reboot into 3.19, and a fresh install of
your kernel debs, things look better:

FWIW:
