Re: Probably 2.4 kernel or AIC7xxx module trouble

[Roberto Slepetys Ferreira]

Hi again,

I passed the parameer: nmi_watchdog=1 to the kernel at the boot.

And after about 2 hours it frozen again, but in the console I found a lot of
messages like this:

smb_proc_readdir_log: name=\....(some directory)....\*, result=-2, rcls=1,
err=2

In the log, I found the same message:

Jul  4 12:35:21 filitico kernel: smb_proc_readdir_long:
name=\Renato(19)\Data Base Nao Utilizados\*, result=-2, rcls=1, err=2

and

Jul  4 12:30:07 filitico kernel: smb_proc_readdir_long:
name=\Renato(19)\Data Base Nao Utilizados\*, result=-2, rcls=1, err=2
Jul  4 12:30:54 filitico kernel: smb_proc_readdir_long:
name=\Renato(19)\Data Base Nao Utilizados\*, result=-2, rcls=1, err=2
Jul  4 12:33:59 filitico last message repeated 3 times
Jul  4 12:34:24 filitico last message repeated 2 times

Do you know what possible it can be ?

Thanks
Slepetys

Re: Probably 2.4 kernel or AIC7xxx module trouble

Hi again,

I did a ps ax|grep -w D, and I got:

Looks like your samba server is upset about some requests its getting.
These probably have nothing to do with your hang.

Did you verify that the NMI watchdog was functioning properly on your
system as outline by the NMI watchdog FAQ in the kernel source Documenation
directory?

I think the problem is elsewhere, please take a look at this message I sent

Is the watchdog enabled in your kernel?  The command line only works
if you have compiled in support for the watchdog.

Re: Probably 2.4 kernel or AIC7xxx module trouble

[Jim Gifford]

Tried that before. Before I thought it was the kswapd problem (see list).
But a few hours after I thought it was fixed, bamm it did it again.

I have monitored ps via this script, but I never see anything out of the
ordinary. I will try again and send a copy to the other guy who is having
the problem to see what results we get.

Re: Probably 2.4 kernel or AIC7xxx module trouble

[Roberto Slepetys Ferreira]

Hi Jim,
It's exacly the same problem, after about 12-24 hour everything locks up,
but I can still ping (sometimes).

But the syslog stops, and I only reboot by hardware, because the CTL+ALT+DEL
doesn't works, and the terminal either.

It's a SMP (dual pentium III) too, but after some tests with single CPU and
NOAPIC parameter to the kernel, the trouble continues.

I have no clue for what kind of tests I can do to generate the trouble, or
for what logs, or files to look for.

Re: Probably 2.4 kernel or AIC7xxx module trouble

Ops....
The linux box halted again, after 12 hours operating normaly.

The more strange is that there isn't any message in the /var/log/message,
the system simples stop to respond, and some strange behavior is that the

Meanning that the Load Average is incompatible with the use of the CPUs.

I really have no idea where to find some clue about what is going on.

Hi,

I upgraded it for the 6.2.36, using RPM and I am making some heavy tests.

Until now, it's ok, and for this kind of tests, the old configuration gave
some trouble.

The "Locking max tag count" messages are normal.  It means the SCSI
driver was able to determine the maximum queue depth of your drive.

6.2.8 is rather old.  I don't know that upgrading the aic7xxx driver
will solve your problem, but it might be worth a shot.  The latest
is available here:

http://people.FreeBSD.org/~gibbs/linux/SRC/

After upgrading, you should be at 6.2.36.

Probably 2.4 kernel or AIC7xxx module trouble

[Roberto Slepetys Ferreira]

Hi linuxers,

I am having a strange halt troubles in my linux box after I installed the
2.4.20 kernel that didn't happen when I was running the 2.2 kernel.

The system works fine for hours or days, and then it halts. The keybord
halts, the remote acess halts, but I still can ping it !

I found some messages in this newsgroup with the same caracteristics, but it
was unsolved.

The system halts easily if I do a large I/O, like reindexing a database,
giving me some messages like: (scsi0:A:1:0): Locking max tag count at 128...

I have a Red Hat 9 distribution instaled in a Intel STL2 server board, with
2 Pentium III 933 Mhz and 512 Mb RAM, 2 scsi disks (18 Mb) and 2 IDE disks
(40 Mb), running in multiple RAID 1 and RAID 0 configurations.

The dmesg gives me the following data about the SCSI:
