This is my first bug report, so be patience.
Recently I decided to try (again) Kernel Modesetting for my old ATI Xpress 200M video card. I don't spend time writing my pain to succeed.

Now it's working.

The problem is the crash upon resume after suspension. With or without X on, it blocks my PC, no magic SYSRQ keys working.

The solution came from google. I paste the solving sentence:

[quote]Edit the file radeon_combios.c and find the line that says /* DYN CLK 1 */
Just before that line add the following:

/* quirk for rs4xx HP DV8002EA laptop to make it resume
* - it hangs on resume inside the dynclk 1 table.
*/
if (rdev->family == CHIP_RS480 &&
            rdev->pdev->subsystem_vendor == 0x103c &&
            rdev->pdev->subsystem_device == 0x309b)
                return;

After changing this, then simply compile your kernel, package it and install it. With KMS enabled it works like a charm.[/quote]

I did this manually and it WORKED.

Tell me which info do I have to post.
