I have getting some problems with my system after a bad reset via ctrl+alt+del. Since then errors related to ACPI and ata6 are reported. Trying to get a solution to this (in a savage way:I am n00b), I started to test the contends in the directory /sys/class/ata_port/ata6/.What I mean with test is looking for a useful information or something that could inspire me to learn or to do a clearer question in a forum. Anyway, apart from this problem, a curious thing happens:

When I use cat or file with the file /sys/class/ata_port/ata6/autosuspend_delay_ms I get "I/O erro". But... using vi I read the contends of the file that is "1".

MAIN QUESTION: Why and how that happens? (This is really freaking me out! vi is more "userland" and cat and file is more "kernelland")

SIDE QUEST: If someone have a idea how to resolve this system problem, I will be very glad! Now, the system boots only using boot parameter "acpi_enforce_responses=lax" (with a good luck!Sometimes even this isn't sufficient to boot and the monitor losts communication (NULL output))"

  • HEY! What is "Server Fault!?". I was logged in Ubuntu community! What to do in order to move this question to a proper site? – Daniel Bandeira Apr 24 '20 at 14:06
  • What is connected to ata6. HDD, DVD, ... ? BTW, ctrl-alt-del can't hurt your hardware. – Gerard H. Pille Apr 24 '20 at 14:08
  • Have a look inside your system, write down what disk devices you see. Start "dmesg | grep ata" and see which are correctly identified. The one that remains is connected to ata6. – Gerard H. Pille Apr 24 '20 at 14:12

  • Please read my previous comment. "dmesg | grep ata" not ata6 – Gerard H. Pille Apr 24 '20 at 14:42

The disk that is not in this list, is the one that is defective.

In your output I see these disks

[ 1.928821] ata1.01: ATA-9: WDC WDS240G2G0A-00JH30, UF450000, max UDMA/133
[ 2.238304] ata3.00: ATA-7: ST3160815AS, 3.CHH, max UDMA/100

A Western Digital Green 240Gb and a Seagate Barracuda 160Gb. Two hard disks. Could it be that the problem drive is a DVD or CDROM? That would be good news: no data lost. If I were you, I would simply remove the sata or pata cable and put it back, you never know it's simply a bad connection.
