Hi,
Some times HVC console on a PPC machine may have pending interrupts and
in this case kdump shutdown sequence created problem by calling
chip->end. This should be chip->eoi(). The attached patch fixes this
issue. Tested on POWER5 box.
Patch generated on 2.6.18-rc6-git4.
It will be helpful if this patch is included in 2.6.18.
Regards,
Mohan.
Call chip->eoi(irq) to clear any pending interrupt in case of kdump shutdown
sequence. chip->end(irq) does not solve this purpose.
