Hi. Jon Smirl wrote: I can't reproduce this, but I think I found the bug from inspection. In the vesafb detection code a pointer wasn't set to NULL correctly. I checked a fix into CVS. Let me know if that didn't fix it. Yes, it fixed that particular problem, but after rmmoding and modprobing about 3 times, there's another: [drm] Debug messages ON PCI: Unable to reserve mem region #1:[EMAIL PROTECTED] for device 0000:01:00.0 PCI: Unable to reserve mem region #1:[EMAIL PROTECTED] for device 0000:01:00.0 [drm:drm_probe] [drm:viadrv_ctxbitmap_next] drm_ctxbitmap_next bit : 0 [drm:viadrv_ctxbitmap_init] drm_ctxbitmap_init : 0 [drm:viadrv_stub_register] [drm:viadrv_stub_register] calling inter_module_register [drm:viadrv_stub_getminor] info count increased 1 [drm:drm_hotplug] [drm] Initialized via 1.4.0 20040819 on minor 0: VIA Technologies, Inc.

Doesn't appear before the patch.   BTW, these two messages didn't appear before your patch PCI: Unable to reserve mem region #1:[EMAIL PROTECTED] for device 0000:01:00.0 PCI: Unable to reserve mem region #1:[EMAIL PROTECTED] for device 0000:01:00.0 Are they an indication of something bad? Also the problem / fix I posted earlier that DRM refuses to install the IRQ handler unless DRIVER_HAS_DMA is defined I think needs fixing. DMA-less drivers could have other useful IRQs. /Thomas --- Thomas Hellstrom <[EMAIL PROTECTED]> wrote: Jon Smirl wrote: What is the stack trace? <Modprobing via> ===== Jon Smirl [EMAIL PROTECTED] __________________________________ Do you Yahoo!?
