Hello Hans,
I used your code new_ihfc_1_5_5 for the kernel compilation. I obtained
several times a kernel panic.
I have a fatal trap 12 (6 times, in the order):
Stopped at sysctl_ctx_free+0x18: pushl 0(%esi)
+0x36: movl
0x4(%eax),%eax
xpt_path_comp+0x19: cmpl $-0x1,0x10(%eax)
camisr+0xcd: movl 0x14(%eax),%eax
+0xb3: movl %eax,0x28(%ecx)
+0xcd: movl 0x14(%eax),%eax
with trace, I have respectively:
2 times:
sysctl_ctx_free()
device_sysctl_fini()
device_ detach()
device_delete_child()
usbd_free_device()
uhub_explore()
usb_discover()
usb_event_thread()
fork_exit()
fork_trampoline()
-- trap 0x1, eip=0, esp=0xd5424d7c, ebp=0 --
then
1time:
xpt_path_comp()
cam_periph_find()
cam_periph_alloc()
passasync()
xpt_async_bcast()
xpt_async()
probedone
camisr()
ithread_loop()
fork_exit()
fork_trampoline()
-- trap 0x1, eip=0, esp=0xd41f2d7c, ebp=0 --
and then 3 times:
camisr()
ithread_loop()
fork_exit()
fork_trampoline()
-- trap 0x1, eip=0, esp=0xd41f2d7c, ebp=0 --
is it really useful in this case to report functions ?
Maybe it can be important: the umass is also a mp3player (Zicplay).
Regards,
MP
