Hi,

recently our Sun-4/670mp has started spewing these messages at
irregular intervals during the most recent rebuild of the world (using
NetBSD 1.5ZA of January 17 source vintage):

esp0: !TC on DATA XFER [intr 10, stat 83, step 4] prevphase 1, resid c0=

f
esp0: !TC on DATA XFER [intr 10, stat 83, step 4] prevphase 1, resid 40=
0

I'm unsure as to whether this is caused by a bug in the driver, or
whether it's the disks we're using which is starting to act up on us;
advice would be appreciated.

Attached below is the complete dmesg output.

Regards,
