[9fans] USB boot fails

[9fans] USB boot fails

[Florian Limberger]

Hello list,

I'm currently trying to boot a Lenovo ThinkPad T410 from a usb pen drive,
using the image from 9legacy.org, but the boot sequence stops at
> sdE0: LLBA 625,142,448 sectors: WDC WD3200BEVT-08A23T1 02.01A02
> WD-WXDD-WXD1A1154275 [mediachange]
with every option I try.

When booting 9pcf I come sometimes as far as
> init: starting /bin/rc
but after then the first message appears and everything seems stuck.
With 9pccpuf I get

WD3200BEVT-08A23T1 02.01A02 WD-WXDD-WXD1A1154275 [mediachange]
and then the same thing happens.

Using another USB port on the laptop, I experienced a similar error like in
this thread:
> http://9fans.net/archive/2012/07/123
but unlike arisawa I don't get a rc shell at the end.
On this other port, the 9pcf kernel fails with

I did then try to add

to the plan9.ini, but the result only is

The paecpu kernel suggested by erik fails nearly instantly with
> panic: e820 scan failed

I also get following messages spilled all through the kernel output:

Is there anything more I can try?

Thanks,

i would give the 9atom kernel a chance at this.  this looks like
an issue with PUIS, and hopefully that's solved.

if you still get "out of choices", you might try *acpi=1 in your plan9.ini.

the original problem is my fault, since the ahci driver was written
before the low-power stuff was put into the ahci standard.

How would I do this? I have played with Plan 9 in qemu, but do not have a
real Plan 9 system otherwise to prepare the pen drive (which is the reason
why I use the 9legacy image in the first place).

Thanks for the fast answer,

you could copy a 9atom kernel onto the pen drive.
	http://ftp.9atom.org/other/9pcf
you would then need to modify the plan9.ini to point to 9pcf
instead of the current kernel.  if they are the same name, then
there is no need to change anything else.

With this kernel I get

(on all usb ports) but the boot process seems much faster.

The *acpi=1 flag does change nothing, neither with the 9legacy nor with the
9atom kernel, but I got the 9legacy 9pcf kernel working with *nomp=1.
That is at least a start.

I got hold of a cd burner and burned a image of 9atom. But while copying
the
data, I get lots of
> cpu0: spurious interrupt 39, last 11
all over the screen (sometimes last 12). There does not seem to be any
progress. Is there a possibility to manipulate the boot options when
booting
 from cd?
