Title: FREQUENT KERNEL PANICS
Post by: LeoTheLion89 on December 24, 2014, 11:15:38 PM
Not sure if this is the right category for this Thread but here's the issue.

I have Rockbox installed on my Philips GoGear HDD6330/17. Lately I've been having quite a few of problems going on with Rockbox.

For example SOMETIMES while hooking to the computer with the player powered on it will KP same when i disconnect it from the computer.

Another example is that since I use my player primarily in my car i have it set for Car Adapter Mode and have it set to idle power-off after 1 minute. Someimes (more often than not) when it is suppose to shut itself off the screen dims with a Kernel Panic.

On a related note: My favourite theme was Boxamp. I can no longer use this theme as it no longer works properly.

Is this my player or rockbox? Do these Kernel Panics mean I will eventually have HDD Failure?

STEPS TAKEN TO TRY TO REMEDY THIS PROBLEM:

WIPED ENTIRE HARD DRIVE - I DELETED EVERYTHING OFF IT AND REFORMATTED THE HDD AS WELL AS RUN INTEGRITY, CONSISTANCY AND SCAN DISK FOR BAD SECTORS EVERYTHING COMPLETED SUCCESSFULLY.

REINSTALLED ROCKBOX AS THE ONLY OS.

I HAVE DONE INSTALLS BOTH MANUALLY AND WITH THE ROCKBOX UTILITY.

Nothing I have done has fixed the problem. I am out of ideas as to why this is happening.

Hi:


I'm owner of HDD6320/17.


I'm also getting continuous Panic errors (could not write sector ....) with no apparent rule for replicating them. Sometimes after finishing playing an album, sometimes when the device goes to sleep, sometimes when powering off by hand...

I've re-checked the disk with linux utilities finding no bad sectors on disk.
I've tried making several partition setups for avoiding potential bad sectors:

- 30 GB FAT32 covering the whole disk.
- 4GB FAT32 only, at the begining of the disk
- 4GB FAT32 only, at the middle of the disk
- 4GB FAT32 only, at the end of the disk

I've tried different firmware builds (http://download.rockbox.org/daily/gogearhdd6330/ ).

I've tried setting different values for the Disk spindown parameter (5s, 60s, 120s, 250s) with no luck.

I'm with you in the obscurity.

peebles, have you tired using it in ext2, ext3, ext4, XFS or JFS formats? have you tried NTFS? what linux utilities did you try?

Huh? Wait...what?

Why on earth would you ever consider using any of these file systems?

On targets where we operate as the sole firmware, we only support a singular file system, FAT32. That is all.

I'm quite sure your assistance is appreciated, but when you answer in these forums the person(s) reading it generally expect those answering to know what it is they're talking about (at least to some degree) instead of suggesting seemingly random courses of action and hoping something sticks.


EDIT: As for the issue(s) at hand, it should be noted that you are using an unstable build for a fairly obscure device that receives little to no specific developer attention other than fixing it up if compilation breaks. The experience is in no way promised to be, or expected to be, free from error.

To quote directly from the main page (http://www.rockbox.org/) regarding this (and every other unstable) port:

Rockbox runs on these players, but is incomplete, less usable or has problems that limit it to advanced users

I was asking about those file systems out of sole ceriousity. Wondering IF they would work. I have prolonged the life of many hard drive by changing it to a different filesystem.

I am well aware that this is a unstable version. But I never had a problem with my HDD1830/17B. I never had any Kernel Panics ever nor did i have the problem where the player would simply NOT play anything at all when powered on Via Car Adaptor Mode.

I also understand that being it's a unstable build it WILL be buggy. What I DON'T understand is why all of the sudden? Why is it the the BoxAmp theme worked perfectly fine for over a year than once these KPs stated to happen that the BoxAmp "Now Playing" screen has disappeared and turned into a failsafe screen but EVERY other part of the theme works perfect?

How is it that Rockbox ISN'T made stable for Philips Players yet other less-popular or less-heard of players have stable builds? And why is there new "Daily builds" for a player that is unstable and has no code change at all in said builds?

EDIT: I also meant to say that I also find the FAT32 FS rather problematic in general and most of the problems with the FAT FS can be solved by changing to NTFS HTFS or any of the LINUX file formats.

They won't, and no you haven't.

The quality of a port depends on the interest in working on it.  If someone has a device and wants to work on it, they may make a very stable port.  We have had people show up and do work on devices that are basically one of a kind, no other person can even run the software. 

And why is there new "Daily builds" for a player that is unstable and has no code change at all in said builds?

Daily builds are compiled every day by a script.  They are exactly what the name says, a build that is compiled daily.  If the code can compile, you will get a build every day.

is there any particular reason that the origin of this post is being ignored? as i have stated:

Also the reason behind these Kernel Panics have still not been explained! If these KPs were due to it being a unstable bulid i would of had it from the getgo on BOTH my HDD1830/17B AND my HDD6330/17 from the getgo.

Someone will take the time to MAKE rockbox work on these players yet wont bother to take the time to make stable builds?

See my answer to you the last time you started a thread asking why no one was working on your player:

I find your position that the Phillips players are in some way popular kind of amusing.

Anyway - even if they are popular with users, that has absolutely NO impact on how popular they are with developers.

The very short answer to all this, basically, is if it is that important to you then you should look into improving the situation for yourself (and the multitude of other Phillips users that apparently highly care about this, of which I'm incredibly sceptical) instead of barking at others and expecting them to do so.
