Hi all, I'm running Linux kernel 2.6.0 Lirc Drivers for 2.6.0 Patch #4 20031231 (http://flameeyes.web.ctonet.it/lirc/patch-lirc-20031231.diff.bz2) [necessary because the machine is running a SMP kernel for which its own lirc_serial causes a hard freeze/crash without the patch] The receiver is a homebrew IR serial receiver (lirc_serial module). It basically works fine until sometimes (no pattern reproduceable) dmesg outputs: irq 4: nobody cared! Call Trace: [<c010c565>] __report_bad_irq+0x2b/0x8c [<c010c64e>] note_interrupt+0x69/0x99 [<c010c970>] do_IRQ+0x16b/0x197 [<c010ad2c>] common_interrupt+0x18/0x20 [<c011e931>] __wake_up+0x45/0x6e [<c038d673>] sock_def_readable+0xa6/0xa8 [<c03e9c66>] unix_stream_sendmsg+0x2bb/0x449 [<c038a1ce>] sock_aio_write+0xbd/0xd6 [<c0159147>] do_sync_write+0x89/0xb4 [<c016b7dc>] kill_fasync+0x3d/0x67 [<c015924a>] vfs_write+0xd8/0x10c [<c015931a>] sys_write+0x3f/0x5d [<c010a3bf>] syscall_call+0x7/0xb handlers: [<f89082d8>] (irq_handler+0x0/0x56d [lirc_serial]) Disabling IRQ #4 and then the LIRC stops working until after reboot. Un-/Reloading the lirc_serial module doesn't work/isn't possible. I've now loaded the lirc_serial module with debug=1 option, if it crashes again, I'll see whether it produces any useful output and let you know. Hope this helps, Regards, Georg -- Georg C. F.
