Helo lkml, I'm trying to write a LDD but I have got a bug. Any ideas what i might be doing wrong?
ret = request_irq(12, handler, SA_INTERRUPT | SA_SHIRQ, "sha1 handler", DEVICE_NAME); printk (KERN_INFO "req irq %d \n", ret); enable_irq(12); I am working on a linux device driver and trying to handle interupts. using the code above I get the log messages below. req irq 0 Unbalanced enable for IRQ 12 BUG: warning at kernel/irq/manage.c:118/enable_irq() [<c0140889>] enable_irq+0x54/0x87 [<c02133de>] __driver_attach+0x0/0x5d [<e0b6f23b>] device_probe+0x16b/0x173 [raggedstone1] [<c01c33ce>] pci_device_probe+0x36/0x57 [<c0213339>] driver_probe_device+0x42/0x91 [<c0213416>] __driver_attach+0x38/0x5d [<c0212e58>] bus_for_each_dev+0x37/0x59 [<c02132a3>] driver_attach+0x11/0x13 [<c02133de>] __driver_attach+0x0/0x5d [<c0212b67>] bus_add_driver+0x6b/0xfd [<c01c3509>] __pci_register_driver+0x47/0x63 [<c0135c67>] sys_init_module+0x1732/0x18b5 [<c015a43b>] do_sync_read+0xb6/0xf1 [<c016e2db>] dput+0x2a/0x119 [<c0102bed>] sysenter_past_esp+0x56/0x79 Has any one seen this type of bug message before? any idea what could be causing it.
