[gentoo-user] hw problems

Hi,

Since last week my gentoo installation start to randomly freeze. The 
first I've detected was during huge disk usage, another was during 
hibernation, etc. I think it might be related to HDD problems, but I 
want to be sure. In kernel log there are some errors, but I'm not able 
to decide if those causes the freezing or not (I've saw such messages 
earlier too, so I'm not sure). So, is there a good diagnostic tool to 
check HW and mainly HDD? What I need to decide is if buying new HDD will 
fix the issue or not.

Thanks a lot

Pat

Install smartmontools then

# smartctl -a /dev/sda

I think Adam answered the OP but I just wanted to understand the kernel log:

- the errors are from device pcieport 0000:00:1c.0
- according to "pci 0000:00:1c.0: [8086:9d14] type 01 class 0x060400", this is should be a 
PCI bridge.

So the error may come from the bridge itself or from a device attached to the bridge, I 
suppose?

- the disk is attached to ata1: "ata1.00: ATA-10: ST2000LM015-2E8174, SDM1, max UDMA/133"
- ata1 is "ata1: SATA max UDMA/133 abar m2048@0xd1133000 port 0xd1133100 irq 122"

Is there a way to understand where the ata1 is physically attached to?
In other words, can one tell from the log if the error comes from the ata1 device or 
something else?

thanks,

raffaele

I think device [8086:9d14] which errors out is a wireless card ... ?

lspci will show the PCI port, but I think the error looks like it is related 
to the wireless card, which is also bouncing like mad.  I'd check the correct 
driver is available and the firmware too, especially if it needs to be 
configured manually (not all are available in linux-firmware).

Looking up that ID via https://pci-ids.ucw.cz/read/PC/8086/9d14 it shows up
as "Sunrise Point-LP PCI Express Root Port #5"

The closest hit i can find otherwise is;
grep '8086 9d' /usr/share/misc/pci.ids
8086 9d60  100 Series PCH/Sunrise Point PCH I2C0 [Skylake/Kaby Lake LPSS
I2C]

Still, I like the idea of removing (or disabling in BIOS) the WLAN
interface to see if that helps. Otherwise i'd be removing any other
non-essential PCIE cards, and reseating any essential ones.

Is the system overheating?

https://en.wikipedia.org/wiki/Machine-check_exception has some links to MCE

Hi,

I want to thank to all for suggestions. The problem was that RAM had 
died. It was slow thus it made me to think that it is HDD.

Thanks again.
