As far as I know, this bug exists on 3.9-rc1 too. When I tried the latest mvebu for-next tree (git://git.infradead.org/users/jcooper/linux.git mvebu/for-next), I got below warning at bootup time and mvneta didn't work (link was never up). I ensured that "ifconfig ethX up" always caused that. Does anyone succeed to boot openblocks-ax3 recently or hit same trouble? ------------[ cut here ]------------ WARNING: at /ssd/ksrc/linux-3/kernel/irq/manage.c:1417 request_threaded_irq+0x64/0x124() Modules linked in: Backtrace: [] (dump_backtrace+0x0/0x110) from [] (dump_stack+0x18/0x1c) r6:c05ad11a r5:00000589 r4:00000000 r3:ed80e000 [] (dump_stack+0x0/0x1c) from [] (warn_slowpath_common+0x54/0x70) [] (warn_slowpath_common+0x0/0x70) from [] (warn_slowpath_null+0x24/0x2c) r8:00000000 r7:ef0a4600 r6:ee9c4d40 r5:00000000 r4:c037378c r3:00000009 [] (warn_slowpath_null+0x0/0x2c) from [] (request_threaded_irq+0x64/0x124) [] (request_threaded_irq+0x0/0x124) from [] (mvneta_open+0x80/0x15c) [] (mvneta_open+0x0/0x15c) from [] (__dev_open+0xa0/0xf4) r6:00001002 r5:c050bb24 r4:ee9c4800 [] (__dev_open+0x0/0xf4) from [] (__dev_change_flags+0x94/0x118) r7:00000001 r6:00001002 r5:00001003 r4:ee9c4800 [] (__dev_change_flags+0x0/0x118) from [] (dev_change_flags+0x18/0x4c) r7:00000000 r6:edd0d380 r5:00001002 r4:ee9c4800 [] (dev_change_flags+0x0/0x4c) from [] (do_setlink+0x2a4/0x7a0) r6:edd0d380 r5:ed80fb4c r4:ee9c4800 r3:00001002 [] (do_setlink+0x0/0x7a0) from [] (rtnl_newlink+0x248/0x45c) [] (rtnl_newlink+0x0/0x45c) from [] (rtnetlink_rcv_msg+0x248/0x278) [] (rtnetlink_rcv_msg+0x0/0x278) from [] (netlink_rcv_skb+0x58/0xb4) [] (netlink_rcv_skb+0x0/0xb4) from [] (rtnetlink_rcv+0x20/0x2c) r6:eea75c00 r5:eea87240 r4:eea87240 r3:c03d5d08 [] (rtnetlink_rcv+0x0/0x2c) from [] (netlink_unicast+0x15c/0x214) r4:ef0a3000 r3:c03d5d08 [] (netlink_unicast+0x0/0x214) from [] (netlink_sendmsg+0x2b8/0x348) [] (netlink_sendmsg+0x0/0x348) from [] (sock_sendmsg+0x88/0xa4) [] (sock_sendmsg+0x0/0xa4) from [] (__sys_sendmsg+0x1c8/0x25c) r7:00000000 r6:00000020 r5:eefccc80 r4:ed80ff64 [] (__sys_sendmsg+0x0/0x25c) from [] (sys_sendmsg+0x44/0x68) [] (sys_sendmsg+0x0/0x68) from [] (ret_fast_syscall+0x0/0x30) r6:be9f367c r5:00000000 r4:5146f675 ---[ end trace a8ceb54233e388b5 ]--- mvneta d0070000.ethernet eth0: cannot request irq 25 Thank you, -- Masami HIRAMATSU IT Management Research Dept.
