Problems with alpha/pci + radeon/ttm
Michael Cree and I have been debugging FDO bug 26403 [1]. I tried booting with `radeon.test=1` and found this, which I think is related: [drm] Tested GTT->VRAM and VRAM->GTT copy for GTT offset 0x202000 [drm] Tested GTT->VRAM and VRAM->GTT copy for GTT offset 0x302000 [snip] [drm] Tested GTT->VRAM and VRAM... 30 Jun 2010 15:21

[PATCH -mm 3/6] ksm: fix ksm swapin time optimization
From: Andrea Arcangeli <aarcange(a)redhat.com> Subject: fix ksm swapin time optimization The new anon-vma code, was suboptimal and it lead to erratic invocation of ksm_does_need_to_copy. That leads to host hangs or guest vnc lockup, or weird behavior. It's unclear why ksm_does_need_to_copy is unstable but the poin... 21 Jun 2010 16:55

From: Andrea Arcangeli <aarcange(a)redhat.com> Subject: always add new vmas at the end Make sure to always add new VMAs at the end of the list. This is important so rmap_walk does not miss a VMA that was created during the rmap_walk. The old code got this right most of the time due to luck, but was buggy when ... 21 Jun 2010 16:55
