boot malfunction

Post by ox85 » Sat Aug 17, 2019 10:48 am

hi there, my linuxmint 18.3 cinnamon 64bit won't boot up
a screen shows up saying something like:

Error parsing PCC subspaces from PCCT
nouveau 000bus mmio read of 0000 fault 02554

BusyBox v1.22.1 (ubuntu 1:1.22.0-15unbuntu1.4 built in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) _
_________

my laptop has always been crashing for months, especially when I use firefox browser & hibernate, so when it crashes I always pull off the plug or force shut down... but this time I can't boot up my laptop normally anymore, the "Error parsing PCC subspaces from PCCT" words show up

can someone please help me asap?

Hello ox85,

that seems to be not a rare problem. What laptop model do you have and is it a dual boot? Maybe you also know, what graphic card is inside?

Have you done this:
BusyBox v1.22.1 (ubuntu 1:1.22.0-15unbuntu1.4 built in shell (ash)
Enter 'help' for a list of built-in commands.

Try booting the installation media and run sudo e2fsck -fvC0y /dev/sd?? on your Linux partition.

Replace the ?? with the proper device designation.

ok thank you i've done that & this came up:

mint@mint ~ $ sudo e2fsck -fvc0y /dev/sda3
e2fsck: invalid option -- '0'
Usage: e2fsck [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
[-I inode_buffer_blocks] [-P process_inode_size]
[-l|-L bad_blocks_file] [-C fd] [-j external_journal]
[-E extended-options] device

Emergency help:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume "yes" to all questions
-c Check for bad blocks and add them to the badblock list
-f Force checking even if filesystem is marked clean
-v Be verbose
-b superblock Use alternative superblock
-B blocksize Force blocksize when looking for superblock
-j external_journal Set location of the external journal
-l bad_blocks_file Add to badblocks list
-L bad_blocks_file Set badblocks list


What should I do next?

There is no need to boot the installer for an fsck. At that "(initramfs)" prompt you get on boot use e2fsck -fvy /dev/sda3 directly. After it finishes, exit to continue the boot. The "error parsing PCC" thing is probably (relatively) innocent, but you may want to try booting with an older kernel if it's a new message.

i've tried that too, it shows up:

(initramfs) e2fsck -fvy dev/sda3
e2fsck 1.42.13 22-may-2015
/dev/sda3 is in use.
e2fsck: Cannot use, aborting.

what to do next friends?

Lovely. Does that mean you use disk encryption? If yes, and if e2fsck -fvy /dev/mapper/mint--vg-root does not work either I'd have to set up a system with disk encryption to check.

Good to know that "just works" on an encrypted disk. I was fearing we'd need some manual setup beforehand. Cheers.

ox85,

Just to clarify your error - you used a lower case 'c' in sudo e2fsck -fvc0y /dev/sda3

My line was sudo e2fsck -fvC0y /dev/sd?? - an upper case 'C'

In any event /dev/sda3 would not have worked with the encrypted /dev/mapper/mint--vg-root

Glad to see you got it straightened-out :wink:

True, but that's probably the first time anyone called me compassionate on the internet. Damn I'm getting old..
