I'm playing with an XP1000 I've installed 2.0-branch on (around a week
ago); boot messages are below.  It's got 4G of swap, but so far none
is in use.

(It's the one I was asking about resetting the SRM console password
on.  I was able to install NetBSD on the disk it tries to boot from,
by using another XP1000.  Still looking for a way to reset the
password, so I can specify a kernel to boot, specify single-user mode,
boot from CD, etc.)

While doing some work on the machine -- mostly compiling, on local
disk -- I started getting some messages logged:

Jul 26 21:19:51 venix /netbsd: esiop0: unable to load cmd DMA map: 35sd0(esiop0:0:0:0): generic HBA error
Jul 26 21:19:55 venix /netbsd: esiop0: unable to load cmd DMA map: 35esiop0: unable to load cmd DMA map: 35sd0(esiop0:0:0:0): generic HBA error
Jul 26 21:19:56 venix /netbsd: esiop0: unable to load cmd DMA map: 35sd0(esiop0:0:0:0): generic HBA error
Jul 27 12:42:42 venix /netbsd: esiop0: unable to load cmd DMA map: 35sd0(esiop0:0:0:0): generic HBA error

According to errno.h, 35 is "resource temporarily unavailable".  More
recently, I'm just getting this message:

Jul 27 17:06:40 venix /netbsd: sd0(esiop0:0:0:0): adapter resource shortage

...rather a lot.  At times, more than one a second.  Right now, only a
few in the past hour.

Is this anything to worry about?
Should the kernel be slowing down its attempts to acquire whatever
resource this is?

I've also been seeing these, though I'm not so concerned about them:

Jul 27 17:00:14 venix ntpd[435]: frequency error 512 PPM exceeds tolerance 500 PPM
(Are alpha system clocks typically so poor?)

Jul 27 17:52:57 venix /netbsd: Warning: received processor correctable error.
(I'm curious what *kind* of correctable error... and I could only find
it documented in my Alpha reference manual in the section on the NT
PALcode support, I think it was.)
