You may consider partition backed swap instead of file backed swap if
that is the case.
Hmm, I can't easily do that, I didn't leave any empty partitions
around as I never considered swapping to a file to be a so bad.
Is swapping to a file so bad under normal conditions?
The message indicates that it took >30 seconds to complete an operation,
so it was timed out assuming the I/O was lost by the device.
In your case it was probably not lost, just delayed for more than 30
seconds by an overloaded filesystem.
Does this mean that this bug is still not fixed in 7.0?
It's not clear whether it's a bug or your disk is just too overloaded to
complete the filesystem operation in a reasonable time period (swapping
to a file is slower than swapping to a partition, which is already
something you never want to do in normal operation). You can increase
the timeout by editing the kernel.
