I've also noticed a new warning from the workqueue code which my scripts
didn't pick up before:

[ 3462.380681] BUG: workqueue lockup - pool cpus=2 node=2 flags=0x4 nice=0 stuck for 54s!
[ 3462.522041] workqueue vmstat: flags=0xc
[ 3462.527795]   pwq 4: cpus=2 node=2 flags=0x0 nice=0 active=1/256
[ 3462.554836]     pending: vmstat_update


Thanks,
Sasha
