Then I tried the INP3 patch by pe1rqx, verson 004 and the kernel goes down as soon as I try to do an actual call on the radio port. It also seems like something goes wrong as soon as I load YAM module The kernel reports: segmentation fault, at each call to ifconfig. The log shows (i removed the timestamps): ---------------------------------------------------------- YAM driver version 0.8 by F1OAT/F6FBB Unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: 00000000 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<00000000>] Not tainted EFLAGS: 00010202 eax: d8859000 ebx: d19ad680 ecx: d19ac160 edx: c029aa88 esi: d19ac150 edi: d19ac040 ebp: d1b387a0 esp: d19bff40 ds: 0018 es: 0018 ss: 0018 Process ifconfig (pid: 813, stackpage=d19bf000) Stack: d8855c01 d19ad680 00000000 00000002 00000000 d19ac150 c142f1e0 c01c933c d19ac150 d19ac040 c01c9939 d19ac150 d2eea540 00000000 d2eea540 c0136ffc d19ac040 d2eea540 d2eea540 d6f5cbc0 00000000 bffffb18 c013563d d2eea540 Call Trace: [] [sock_set_timeout+60/160] [sock_getsockopt+73/816] [shmem_file_setup+76/352] [shmem_unuse_inode+93/320] [shmem_unuse_inode+222/320] [system_call+51/56] Code: Bad EIP value. ------------------------------------------------------------ I was thinking of giving up and do without INP3, but if anyone knows this problem and perhaps a hint where to look?? I used the patch which was meant for a 2.4.19 prerelease, but agains the official 2.4.19 kernel source. I cant find any other info on this than: http://sharon.pi8zaa.ampr.org/users/pe1rxq/inp3.html Btw. What is the "sock_orphan patch"? 73 de LA7ECA
