RE: [PATCH] bug w/ shared interrupts

Hi,

I don't know whether you are referring to my patch. But if so,
please try a following patch. The patch for sharing vector I sent
before contains a bug and I think this might cause a similar problem.

Thanks,
Kenji Kaneshige


This is a patch to fix the following bug:

Register_intr() changes pin->low32 even when it overrides the
interrupt info. This destroys the value of pin->low32 which is already
set by set_rte() or other staffs.

This patch is against linux-2.6.6-rc2 with share_vector.patch applied.
