             Bug #: 53291
           Summary: Failed to allocate a buffer at CAYMAN
    Classification: Unclassified
           Product: DRI
           Version: DRI CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libdrm
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: v10lator@myway.de


I see this error randomly with different games. Good reproducable with
minecraft (appears at the first minutes of gameplay).
radeon: Failed to allocate a buffer:

radeon:    size      : 4096 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 2
This shows up in dmesg:

Also (don't know if that is related or if I should open a new report for it) I
randomly get a similar error. Good reproducible by playing two instances of
minecraft at the same time:
radeon: Failed to allocate a buffer:
