[parisc-linux] console on ttyS0 broken with 2.6.9-bk6-pa1 ?

[parisc-linux] console on ttyS0 broken with 2.6.9-bk6-pa1 ?

[Helge Deller]

I just compiled/booted the latest CVS kernel (2.6.9-bk6-pa1) which seems to boot fine.
Sadly using a serial console is broken. Any ideas ?

This is the bootlog in minicom:

Boot image contains:

Sorry I could very help but I experiment a similar pb on my c110:

After this , on this c110 (and b180) model, there are not any more messag=
es
display (since release 2.6.9-rc2-pa1?) on serial console (no way to test
sti one :( ) before :
0x00000009}
lp: driver loaded but no devices found
Generic RTC Driver v1.07
(ie just after sti switch should occur ?)

The same but the message is weird for me:
0x00000009}
0x00000009}
0x00000009}
etc

(Note that one of this line was already displayed before "lp: driver..."
?)

Anyway (may be was I not enough patient) the system never came up 
(I couldn't even launch a TOC to grab some piminfo:  the time stamp of wh=
at
I read was date May 23 ... when the hw system clock was well Oct 23 ...?)=


Also a simiar pb on the n4k, the message was:
'io scheduler noop registered'
'io scheduler noop registered'
etc

And the system didn't bring up too (I almost waited 10 mininutes before
reset it)

OTC my b2k with 32bit kernel boot fine without any pb of any kind (all me=
ssages
are well displayed :)

 Cheers,
    Joel
