Re: Debian kernel boot failure on Alpha [was Re: systemd FTBFS]
Dear Michael,
just a quick note because it might be related or at least helpful:
I have had a similar problem than you, i.e. no generic Linux kernel v4.x
from Debian runs or ran on my Alpha gear (the newest one is a PWS 500au
with EV56). E.g. this is the output of a tried boot with a generic Linux
kernel v.4.3.0-1 from Debian:
```
>>>show boot*

boot_file
boot_osflags root=/dev/nfs ip=dhcp console=tty1
console=ttyS0,9600n8

```
The older 3.16.x kernel worked without a problem on my machines though.
Hence I thought that maybe something was changed in the v4.x kernels
that made them incompatible with pre EV6 CPUs. There were some messages
about enabling BWX (starting with [1]), but as it should still work with
EV56 when enabled I wondered if my problems were related at all.
[1]: https://lists.debian.org/debian-alpha/2014/09/msg00000.html
Mid of 2015 you wrote on [2] that you haven't yet enabled BWX, so also
for my other gear (LCA4, EV4, EV45) this couldn't be the problem, as it
wasn't enabled yet.
[2]: https://lists.debian.org/debian-alpha/2015/06/msg00001.html
As no v4.x kernel worked with my machines I stayed with the working
3.16.x kernels.
Until recently I didn't have a reason to also try the SMP variant of the
v4.x Linux kernels, but now that I have a DS20E and had the same
problems with the generic Linux kernel v4.x from Debian I also tried the
SMP variant on it.
And the SMP variant of the v4.x kernel just works (tested with
"4.8.0.2-alpha-smp", "Debian 4.8.11-1" from 2016-12-02 to be exact).
Today I thought about also trying the SMP variant of the v4.x kernel on
my older Alpha non-SMP machines - well, there's no reason that an SMP
kernel shouldn't work on a non-SMP machine I believe, if it is not
prohibited by some configuration.
And guess what, the SMP v4.x kernel also works there.
For my AlphaStations 200 and 255 I had to disable AGP support with
`agp=off` to be able to continue booting after the agpgart message. I
don't really know why it bothers these machines, but disabling AGP
support on a system without AGP ports doesn't hurt, so no issue.
I currently still have a problem with the kernel level IP
autoconfiguration on the older machines, but the SMP kernel seems to be
booting on all machines.
Find the dmesg output for my PWS 500au below.
So maybe you could try the v4.x SMP kernel on your XP1000 and see if it
works there, too?
Please CC me because I'm not on the list.
Cheers,
Frank
