5.0.18: "Bad scbptr 255 during SELTO"

I just installed Linux kernel 2.0.34, updated with the 5.0.18 Adaptec
driver. This setup seems to work reasonably so far, except that I
often get error messages like
(scsi0:-1:-1:-1) Bad scbptr 255 during SELTO.
(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
SCSISEQ = 0x12 SEQADDR = 0xb SSTAT0 = 0x10 SSTAT1 = 0x8a
during startup. This is not always the case, however--sometimes I
get what looks like a success message:
(scsi0:-1:-1:-1) Allocating initial 30 SCB structures.
Are the error messages something that I should be concerned about?
Further information: I'm running two Adaptec 2940UW controllers,
and I use
append="aic7xxx=reverse_scan,verbose"
in my /etc/lilo.conf. Please see below for an excerpt from my
startup messages.
