[parisc-linux] 2.4.18-pa35 SMP process hangs on a J200

[Thibaut VARENE]

Hi all,

We hung again our A500  :/

Still the same symptoms.

It seems that it is the seti process that hung it:
We can access info in /proc/1/, but nothing about the seti process:
see the following:
[varenet@mkhppa3 ~]$ cat seti1/pid.sah
5972
[varenet@mkhppa3 ~]$ ls /proc/5972/

And the command would not return.

We issued a 'w' that got hung too, but we can still access its proc info:
[varenet@mkhppa3 /proc]$ cat 6576/cmdline
w
[varenet@mkhppa3 /proc]$ cat 6576/mem
cat: 6576/mem: No such process
[varenet@mkhppa3 /proc]$ cat 6576/status
Name:   w
State:  D (disk sleep)
Tgid:   6576
Pid:    6576
PPid:   1
TracerPid:      0
Uid:    1001    1001    1001    1001

Of course, a 'kill -9 6576' would do nothing.

We can also access the info about the distributed.net client, which 
seems to be hang too:
[varenet@mkhppa3 /proc]$ cat 224/status
Name:   dnetc
State:  D (disk sleep)
Tgid:   224
Pid:    224

Now we are about to test with only 2 dnetc, no seti, to see whether it 
crashes or not.

We'll keep the m-l informed.
