hm, i think these were all fixed a long time ago, via:

f6d87f4: genirq: keep affinities set from userspace across free/request_irq()
612e368: genirq: fix the affinity setting in setup_irq
6c2e940: x86: apic honour irq affinity which was set in early boot

Kumar, could you please check v2.6.28-rc9 to see whether all issues are
fixed?

not really a regression but a long-standing inconvenience/bug of the debug
symbols of relocatable kernels. (ever since relocatable kernels were added
in '06 or so.) Nevertheless we queued up a revert of the defconfig change
for .29, to not expose it in the defconfig:

f269b07: x86: revert CONFIG_RELOCATABLE=y defconfig change

so i think it can be taken off the regressions list.

This bug still occurs. So, it still needs to be on the regression list.
I have not yet seen any replies to my bug report.

It's a bug, yes, not a regression. It should be fixed if possible, but
it's not a regression nor a hideously critical issue.

I got a reply to my bug report and I tested the patch provided by Dave
Airlie. It seems to solve the problem. The error doesn't occur anymore
when it's applied.

It seems that the bug #12216 is the same bug. I tested the patch posted
in it and everything is back to normal. Many thanks.

Could you provide the full filecache listing(the 'size' field may
provide some info), and the contents in /proc/dri/0/*?

Simply being "deleted" does not mean that they are leaked files.
shmem files are special.
