Ubuntu – COMRESET failed and slow boot times

12.04bootlenovosataultrabook

I've been having slow boot up times with a fresh install of 12.04.2 LTS. I see this in my syslog:

Jul  2 13:42:56 victor-Lenovo-U310 kernel: [20058.135895] ata1: link is slow to respond, please be patient (ready=0)
Jul  2 13:43:25 victor-Lenovo-U310 kernel: [20087.780435] ata1: COMRESET failed (errno=-16)
Jul  2 13:43:30 victor-Lenovo-U310 kernel: [20092.806429] ata1: COMRESET failed (errno=-16)
Jul  2 13:43:30 victor-Lenovo-U310 kernel: [20092.806436] ata1: reset failed, giving up

I tried the the following kernel parameters with no success:

libata.force=nohrst libata.force=nosrst libata.force=norst libata.force=noncq

I have tried re-installing 12.04.2 LTS and have also installed 13.03 and still nothing has worked. Also set the ATA controller to Compatible (IDE), AHCI, and RAID, and none of those fixed the problem. Reset my BIOS to factory settings, also nothing.

My specs:

  • Model: Lenovo IdeaPad U310
  • Processor: 1.7 GHz (2.6 GHz max turbo) Intel Core i5 3317U
  • RAM: 4GB (DDR3)
  • Graphics: Intel HD Graphics 4000
  • Storage: 500GB (5,400 RPM) HDD + 24 GB SSD (Can't use it for some reason)

Best Answer

found : libata.force=noncq but this add-in commandline isn't complete

added by changing: 

GRUB_CMDLINE_LINUX="libata.force=16.00:noncq"

in /etc/default/grub. after exit-save 

update-grub

found also : 

libata.force=8.00:noncq 
tried libata.force=16.00:noncq

for dmesg shows

>> ata3: SATA max UDMA/133 port i16@0xbc00 bmdma 0xcc00 irq 11 
>> ata4: SATA max UDMA/133 port i16@0xc000 bmdma 0xcc08 irq 11    
>> ata5: PATA max UDMA/133 port i16@0xc400 bmdma 0xcc10 irq 11

doesn't resolve

>>>ata5: SATA max UDMA/133 port i16@0xbc00 bmdma 0xcc00 irq 11
>>>ata5: link is slow to respond, please be patient (ready=0
>>>ata5: COMRESET failed (errno=-16)

hmm

ok, solved it.. but this makes it outside the situation you guys/girls have i removed a Promise ATA card (133/TX3) and mounted the boot-disk at onboard port. That made the SATA work - sigh.. knew it.. it was something simple..
