hello, i have a problem with getting the ir (homebrew) hardware working. i hope i can find some help with this list ... (I'm using debian 3.0, kernel 2.4.18, on an diskless machine (nfs-root)) I compiled the serial kernel support as module which is not inserted during bootup (for testing, no serial-configuring-action during bootup is done - gpm is disabled). With "modprobe lirc_serial" the compiled module is correctly inserted (obviously, i get the message "lirc_serial: auto-detected active low receiver") But with executing "mode2" now, i get a seg fault and a kernel panic: --------------------------------------------------------------------- Segmantation fault ['prompt']: Unable to handle kernel paging request at virtual address 205b2070 printing eip: c010e673 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c010e673>] Not tainted EFLAGS: 00010087 eax: c3813494 ebx: c26d1f94 ecx: 205b2070 edx: 00000001 esi: c0245f58 edi: 00000001 ebp: c0245f40 esp: c0245f28 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0, stackage=c0245000) Stack: c0245f58 c0245f58 0000000 c3813494 00000086 00000001 00000001 c38126f4 c2b08800 20000001 0000004 c0245fa8 3d301772 000d29bc c0107ddf 00000004 00000000 c0245fa8 0000080 c027c980 00000004 c0245fa0 c0107f4e 00000004 Call Trace: [<c3813494>] [<c38126f4>] [<c0107ddf>] [<c0107f4e>] [<c0105150>] [<c0109d88>] [<c0105150>] [<c0105173>] [<c01051d7>] [<c0105000>] [<c0105027>] Code: 8b 01 85 45 fc 74 4d 31 c0 9c 5e fa c7 01 00 00 00 00 83 79 <0>Kernel Panic: Aiee, killing interrupt handler!
