I've tried each of these to no effect. The problem always still occurs. I
noticed that in dmesg it says that apic is disabled usually anway. As far as I
know it's not needed on single processor systems. Turning off acpi seemed to
cause the wireless card to be started later, so ntp sync failed. But that's all
I saw different to normal.

I thought about trying other distros to see if that changes things. The trouble
is with only 128MB and a 600MHz P3, I'm limited in choice. As Ubuntu is debian
based I thought it best to stay away from other similar distros. Since I have
Zenwalk 1.2 (formally Minislack) on a mag cover cd I thought I'd start there.
But sadly, that didn't show any improvement. 

I have looked into ALSA and found that the driver is for the previous revision
i.e. es1968 rather than my es1978 and that sound capture is not supported. As
the specs were never released for this chipset it seems likely that there will
be problems. I must confess I've no idea how the sound system works so I can't
really comment, though I'd be surprised if this driver will see any more updates.
