Subject: 2 (minor) Alpha probs in 2.5.51

(This is with rth's exception patch to fix the mount problem).

1) If compiled for the LX164 platform it is missing a number of symbols
at link time (fine if built generic):

arch/alpha/kernel/built-in.o(.data+0x3030): undefined reference to
`cia_bwx_inb'
arch/alpha/kernel/built-in.o(.data+0x3038): undefined reference to
`cia_bwx_inw'
.
.
.
(and a handful more)

2) This is a kind of subtle one. Straight after boot up if I run 'w'
or 'top' I get the warning:

Unknown HZ value! (831) Assume 1024.

This value creeps up:

Unknown HZ value! (958) Assume 1024.

over a period of a few minutes till the warning goes away.

I had this exact same problem the other day, and this is fixed in -bk now.
Remove the #include <asm/io.h> in include/asm/pci.h.

Fixed in current TOT.

Dunno. Could be your clock chip is going bad.

Great.

Don't think so; with 2.4.19 it seems to be fine, and it returns to the
low value after restarting a kernel from MILO even without powering the
machine down or returning to AlphaBIOS.

On the other hand, the code hasn't changed since 2.4 either.

I had a DS10 here that had, what appeared to be, a bad crystal. The clock
would start at about 1/2 to 3/4 the expected clock rate and over about 20
minutes would move towards what it should be at. It appeared to overshoot
the right clock-rate and then below until the oscillations would dampen
down to the correct rate.

I was doing RTLinux work on it so a bad clock wasn't acceptable. It lives
in the garage now since I had a another DS10 that worked right. I never
found what was actually going wrong with it or found a fix.

I would argue, though, that the Alpha clock itself is a crazy thing and
shouldn't be expected to work right :)
