[parisc-linux] test11-pa2 & serial console on C3k success, siimage problems

[M. Grabert]

Hi PA,

First of all thanks for all the people involved in getting
2.6 working on PA-RISC, especially those who fixed the
serial console issue!


It seems to work for me (after initial testing), however I ran into
some other problems, for which I would be very grateful if they
can be resolved aswell:

As I needed some additional hard disk space I bought a 120GB hard disk.
Since I'm not a particular rich person, I could only afford a IDE version,
not a SCSI hard drive.
As mentioned in previous posts I'm using the internal NS87415 IDE
controller of the C3000 to drive the Seagate IDE hard disk (ST3120022A).

It works, but is limited to non-dma transfers and therefore it is not
very performant (about 3.3MB/s reading, writing even slower).
I've been also told I'm quite brave for using the internal IDE controller,
since it was never been used/tested for this purpose before.

Therefore I did the most reasonable thing and got a IDE PCI controller.
Unfortunately the only (new) ones on the market you can get are based
on the Promise chipset or the SiliconImage chipset. I got one with the
SiliconImage chipset, since they also support ATAPI commands, whereas
the Promise doesn't.


It seems there is a bug in either the kernel or (more likely) in the
SiliconImage driver, both with the 2.4.23-pa3 and the 2.6.0-test11-pa2
kernels.

The 2.4.23-pa3 kernel allows me to boot with the siimage driver compiled
in (I disabled the support for the NS8741 in the kernel). However the kernel
complains about 'lost interrupts' on boot and won't allow me to use
the hard disk (read errors, see
http://www.cs.ucc.ie/~xam/siimage/readerrors-2.4.23-pa3.txt )
I the 2.4 kernel was compiled with DMA support, but I also tried to
boot with 'ide=nodma', with exactly the same results.

The 2.6.0-test11-pa2 kernel is configured similar, but generates a
'you system ate a SPARC' kernel ooops:

The full bootlogs/config/System.map can be found here:

I also placed the bootlog/config/System.map for my current (working)
config - ie. using the internal NS87415 IDE controller - here:
   http://www.cs.ucc.ie/~xam/siimage/working-with-NS87415/


Any help would to make the SiliconImage card working would be appreciated!
I think many people also want to 'upgrade' their system by putting in
an additional hard disk at one stage in the future, and will hit the
similar problem that there is currently no working IDE PCI card for Linux/PA


Thanks alot in advance,
  Max
