AW: [Fedora-xen] ati-driver and xen kernel --> black screen --> fc6 Test2 ok

[thomas.vonsteiger at bluewin.ch]

Hello,

 

Now with FC6 Test2, xen Kernel and ati-driver-installer-8.27.10-x86.run
display with high resolution on HP Notebooks nw8440 and nc8430 is running.

This type of notebooks with cpu's T2500/T2600 are not VT enabled from OEM
site. With latest BIOS there is no config to enable VT.

 

(XEN) Initializing CPU#0

(XEN) Detected 2161.335 MHz processor.

(XEN) CPU: L1 I cache: 32K, L1 D cache: 32K

(XEN) CPU: L2 cache: 2048K

(XEN) CPU: Physical Processor ID: 0

(XEN) CPU: Processor Core ID: 0

(XEN) VMX disabled by Feature Control MSR.

No, it's called a lock bit because it is sticky once set. The intention is
presumably to allow OEMs an easy way (in their BIOS) to disable VMX on their
systems if they don't want to have to support it.

Betreff: [Fedora-xen] ati-driver and xen kernel --> black screen

 

Hi,

 

I can testing HP Notebooks nw8440 and nc8430 with VT enabled CPU's
(T2500/T2600) and fc5 to have fullvirtualitation on a notebook.

With the latest smp kernel 2.6.17-1.2174 and
ati-driver-installer-8.27.10-x86.run (generate rpm's) everything is working.

If I try to boot the latest xen kernel 2.6.17-1.2174  in runlevel 5 with the
same ati driver I get a black screen, no display, no console.

The same xen kernel can boot without problem in runlevel 3 and then I have a
console.

Has anybody a solution for this problem ?
