[9fans] USB boot fails

["Florian Limberger" <flo@snakeoilproductions.net>]

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
> usb/hub... usb/disk... bad authentication password
> bad authentication id

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
> boot: can't connect to file server: '/boot/kfs' does not exist
> panic: boot process died: unknown
> [...]

I did then try to add
> readparts=
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:
> mpintrenable: multible botch irq 11, tbdf 5000000, lo 00000049, n

Is there anything more I can try?

Thanks,
