When streaming a lot of data and the RZ/A1 can't keep up, some status bits will get set that are not being checked or cleared which cause the following messages and the Ethernet driver to stop working. This patch fixes that issue. irq 21: nobody cared (try booting with the "irqpoll" option) handlers: [<c036b71c>] sh_eth_interrupt Disabling IRQ #21 Fixes: db893473d313a4ad ("sh_eth: Add support for r7s72100") Signed-off-by: Chris Brandt <chris.brandt@renesas.com> Acked-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> --- v3: * add RZ/A1 to subject line v2: * switched from modifying eesr_err_check to modifying eesipr_value --- drivers/net/ethernet/renesas/sh_eth.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
