Running Mandriva 2007 (2.6.17-5mdv #1 SMP kernel) with lirc-0.8.1-0.20060722.4.2mdv2007.0.i586.rpm installed, I'm having persistant Bad EIP errors when lircd terminates (normally on system shutdown or reboot). Compiling from the 0.8.1 (nonCVS) source did not improve matters. The hardware using lirc is a Hauppauge WinTV bt878 card with Hauppauge remote. Here's the relevant material from /var/log/messages: kernel: BUG: unable to handle kernel paging request at virtual address f91856ba kernel: printing eip: kernel: f91856ba kernel: *pde = 378de067 kernel: *pte = 00000000 kernel: Oops: 0000 [#1] kernel: SMP kernel: Modules linked in: snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq floppy snd_pcm_oss snd_ mixer_oss cx8800 cx88xx ivtv snd_via82xx rivatv gameport snd_ac97_codec ipv6 snd_ac97_bus snd_pcm snd_timer snd_page_alloc snd_mpu401_uart snd_rawmidi usblp snd_seq_device snd soundcore xt_limit ipt_LOG xt_tcpudp xt_state ipt_MASQUERADE ip_conntr ack_ftp iptable_nat ip_nat ip_conntrack nfnetlink iptable_filter ip_tables x_tables af_packet video thermal fan container b utton battery ac ide_cd binfmt_misc cryptoloop loop aes supermount sg dm_mod cpufreq_ondemand cpufreq_conservative cpufreq_ powersave freq_table processor via_agp bt878 tvaudio bttv i2c_algo_bit btcx_risc tveeprom tuner saa7134 video_buf compat_io ctl32 v4l2_common v4l1_compat ir_kbd_i2c ir_common videodev nvidia agpgart i2c_core evdev tsdev usb_storage usbmouse ehci_h cd usbhid uhci_hcd usbcore ext3 jbd sd_mod sata_via libata scsi_mod kernel: CPU: 0 kernel: EIP: 0060:[<f91856ba>] Tainted: P VLI kernel: EFLAGS: 00210282 (2.6.17-5mdv #1) kernel: EIP is at 0xf91856ba kernel: eax: 00000000 ebx: f9185530 ecx: 00000000 edx: 00000000 kernel: esi: f9188100 edi: 00000000 ebp: f76d3fe4 esp: f76d3fcc kernel: ds: 007b es: 007b ss: 0068 kernel: Process lirc_dev (pid: 2882, threadinfo=f76d2000 task=f74c6a70) kernel: Stack: f918673b 00000000 00000000 f9185530 00000000 00000000 00000000 c0101005 kernel: f9188100 00000000 00000000 00005067 00004067 kernel: Call Trace: kernel: <c010425d> show_stack_log_lvl+0x9d/0xd0 <c0104497> show_registers+0x1b7/0x240 kernel: <c0104652> die+0x132/0x330 <c011c5d6> do_page_fault+0x276/0x670 kernel: <c0103cc3> error_code+0x4f/0x54 <c0101005> kernel_thread_helper+0x5/0x10 kernel: Code: Bad EIP value. kernel: EIP: [<f91856ba>] 0xf91856ba SS:ESP 0068:f76d3fcc A saa7130 based tv card is also installed, and may be related to the problem. This card does not have a remote, but the saa7134 module requires that the ir_kbd_i2c module be loaded (this was not the case under Mandriva 2006, where this hardware setup worked without any such problems). When these modules are present, lirc behaves oddly (when testing with irw I frequently receive digits interspersed with the normal irw button-press output). These extra signals seem to interfere with the operation of lircd, and they definitely interfere with the use of lircmd. I can fix this problem by running "rmmod saa7134 ; rmmod ir_kbd_i2c" (although it's hardly ideal as it disables the saa7130 card). Removing these modules does not help with the Bad EIP error, however. So, at this point, I'd welcome all recommendations. First and foremost, how to run lirc without this problem. I appreciate your time. Thanks in advance for the help! |
