Re: [BUG] HVR-1500 Hot swap causes lockup

 Hmmm.? I can probably get another computer, but it doesn't have Linux on it.? Could I use a live CD to do it?

Since it is hard locking and I am completely unfamiliar with HVR-1500
and PCI hot plugging a netconsole is the best thing I can offer...

1) You will need a second computer connected to your laptop via a LAN.

2) Find out the IP address of the computer that is not your laptop.

 $ /sbin/ifconfig 

eth0      Link encap:Ethernet  HWaddr 
          inet addr:192.168.1.150  Bcast:192.168.1.255 Mask:255.255.255.0
.....

So, in this case the IP address is 192.168.1.150

3) Start netcat in a terminal on this system.

  $ netcat -u -l -p 666

4) Now, on your laptop run the following commands as root in a terminal.
NOTE: replace 192.168.1.150 with the IP address you found in step 2.

  $ dmesg -n 8
  $ modprobe netconsole netconsole=@/,@192.168.1.150/

5) netconsole: network logging started should appear in the terminal
where you ran netcat.

6) Try to reproduce the hard lock on your laptop and include the output
from netcat.

Let me know if this works.

Also, please continue to CC the v4l list.

Cheers,
