Kernel Bug in ATA or SMART area
Axel Uhl
the ATA or SMART code in the kernel / modules. I have a cron job that
every so many hours captures the disk temperatures. I "hdparm -y" my
disks when they are not used. It seems that when the cron job runs that
spins up the disks to access their temperature using smartctl, if during
this time certain other interactions happen, the kernel raises an exception.
The smartctl command I'm using is:
/usr/sbin/smartctl -a $devfull >/var/local/snmp/smart-$dev.TMP
Here is one such exception from the syslog:
Feb 10 06:57:01 homemp3 /USR/SBIN/CRON[18271]: (root) CMD

I suppose the hadam3p_um_6.14 command is part of my BOINC installation,
doing a climate simulation. However, the problem has also occurred with
this program not running.
Here's the output of scripts/ver_linux:
If some fields are empty or look unusual you may have an old version.

As a result of the exception, the system becomes very unresponsive. Any
sort of I/O seems to have very poor response time. Ping times in the
gigabit network suddenly take several tens of milliseconds. It seems
this may have to do with the IRQ10 being somehow affected, but I'm not sure.

This is one crowded IRQ line. Two ATA controllers, sound card, USB
host and NIC on the same IRQ? Does the ATA timeout always occur on
the command b0?
Thanks.

Judging from your initial message and this one, it appears that the
problematic disk is driven by sata_via, but sata_via shares IRQ with
an awful lot of other junk.
Suggestions:
1. Enable IO/APIC support in the kernel. According to your previous lspci
the chipset does have one. This should reduce IRQ sharing and make IRQ
handling generally better. If there's still some sharing going on,
try moving PCI cards to other slots.
2. Move the problematic disk around to e.g. the Promise controller. Do the
stray exceptions persist? If so, then it's the disk that's at fault.
As long as the libata's error handling recovers, things should work anyway.
3. (Unrelated but...) Why use Old IDE to drive the VIA PATA controller?
Just use pata_via for that one, enable SCSI SR+SG support, and disable IDE.
Axel Uhl
pata_via but was unsure which IDE driver to disable. The kernel
rebooted fine. The following appeared in my syslog when the smartctl
command spinned up the disk:

At least it seems that the kernel recovered better from this exception
than before. In particular, IRQ10 didn't get disabled and so I/O
continued to work fine. Thanks for the hint.
Would you consider the exception above a serious problem that should be
taken care of somehow?
Best,

That would be VIA82CXXX. But all your PATA/SATA controllers are now driven
by libata, so you can disable IDE, i.e. set CONFIG_IDE=n.

Apparently this disk likes to complain when issued a SMART command while spun
down, but as libata EH recovers nicely there's no real reason to worry.
Axel Uhl
BTW, how do you know that all my PATA controllers are driven by libata?

This to me looks at least as if the VIA IDE driver still recognizes the
IDE disks.

The SMART error isn't likely to be related to the nobody cared.
Neither is the switch to libata driver. One possibility is that the
IRQ line is shared with yet another device which the corresponding
driver didn't take care of (there was an i2c controller raising
interrupt behind the driver's back).

In itself, it's not dangerous at all although repeated occurrences
could be annoying.
Thanks.

and pata_via is libata's replacement for IDE's via82cxx.
Since you kept both drivers enabled, it seems that IDE's via82cxx won the
race to claim the hardware. Bummer.
Just disable CONFIG_IDE.

Changes in /etc/fstab were necessary because /dev/hd[abcd] now became
/dev/sd[cdef]. Everything else seems to work normally for now. I'll
check if this also makes the exception go away altogether.
Thanks again and best regards,
