Hello:
I run the oklinux with modification to suit for the Android goldfish. Things
sounds good to boot earlier from Android Emulator. But there is a kernel
panic as following and it goes into the KDB:
[ 0.427141] Got unexpected IPC from 0x80000001
[ 0.428372] Kernel panic - not syncing: unexpected ipc message
[ 0.430000] Rebooting in 1 seconds..Linux exit status: 5
--- KD# User: Linux exit ---
>
I check the source code of oklinux and find these errors are from here:
if (sender.raw == L4_nilthread.raw)
irq = mask_to_irq(&num);
else {
printk("Got unexpected IPC from 0x%x\n", sender.raw);
panic("unexpected ipc message");
}
it seems that interrupt_loop got an IPC from unexpected thread
(L4_ThreadId_t.raw = 80000001). I want to know what this thread is from KDB.
I try to use the KDB debugger but it seems to be very tricky. Does anybody
tell me how to debug this unexpected thread.
Thanks a lot.
Cheng Guanghui
