RE: Errors Help need.



I have no idea. There is nothing in the traces that indicates a
memory handling error. I would expect a <handle_mmu_bus_fault+b4/b8>
entry. I guess that you have checked that IPC is enabled in the
kernel. Anyway I think that this is not related to the CRIS port
itself. Did the bluez guys recommend any particular kernel version?
2.4.20 may be too old.

Hi, 

The bluez guys said to update bluez?. Kernel again panics when I try to
write something to a bluetooth socket. However this time, every trace
leads to different results. However they have things in common. Below
you can find two traces, given by the same program :):
Trace; c0008408 <printk+0/144>
Trace; c005d836 <sys_msgsnd+ea/284>
Trace; c005d992 <sys_msgsnd+246/284>
Trace; c005da6c <sys_msgrcv+9c/2de>
Trace; c0008408 <printk+0/144>
Trace; c005fcfe <sys_shmctl+4de/786>
Trace; c005faf8 <sys_shmctl+2d8/786>
Trace; c005d656 <sys_msgctl+5e2/69c>
Trace; c008b0fc <flash_probe+80/c8>
Trace; c005e4c6 <semctl_nolock+d2/1fa>
Trace; c005c910 <grow_ary+48/6c>
Trace; c005e39a <copy_semid_to_user+4e/a8>
Trace; c005c910 <grow_ary+48/6c>
Trace; c005c91a <grow_ary+52/6c>
Trace; c0087a8c <e100rxtx_interrupt+2e/1a4>
Trace; c005c910 <grow_ary+48/6c>
Trace; c005c91a <grow_ary+52/6c>
Trace; c005c962 <ipc_addid+2e/90>
Trace; c000407a <rest_init+2a/2c>
And another trace (oops:0002)
Oops: 0Trace; c0008408 <printk+0/144>
Trace; c005d836 <sys_msgsnd+ea/284>
Trace; c005d992 <sys_msgsnd+246/284>
Trace; c005da6c <sys_msgrcv+9c/2de>
Trace; c0008408 <printk+0/144>
Trace; c005fcfe <sys_shmctl+4de/786>
Trace; c005faf8 <sys_shmctl+2d8/786>
Trace; c005d656 <sys_msgctl+5e2/69c>

The trace seems that there is some share memory error? What do you think
this can caused by? 

Thanks in advance
