Hi,
I updated my -CURRENT AlphaStation 200 4/100 to sources from around this
morning.
I get a fatal kernel trap in tga_init()
-----------
tga0: Reserved 0x8000000 bytes for rid 0x10 type 3 at 0x88000000
fatal kernel trap:
trap entry =3D 0x2 (memory management fault)
faulting va =3D 0x88100050
type =3D access violation
cause =3D load instructon
pc =3D 0xfffffc000064af10
ra =3D 0xfffffc000065043c
sp =3D 0xfffffc00007eba90
usp =3D 0x0
curthread =3D 0xfffffc00006feb58
pid =3D 0, comm =3D swapper
Stopped at tga_init+0x70: ldl t0,0x50(t3) <0x88100050> =20
-------------
The old kernel (FreeBSD 5.2-CURRENT #1: Sat May 1 15:46:05 CEST 2004)
works fine. The new kernel only adds device pcm, and is cross-built on
an AMD Athlon machine, because building it native takes very long :)
Is there anything I can do to help? I have a serial console setup, but
didn't use a debugger over it yet. I don't need the tga device, so as
last resort I could just comment it out. The machine is basically a box
for testing, so I don't mind trying things out with it :)
Thank you!
Regards,=20
