Hi nic2109 & Everitt,

Thanks for the logs, the reason that MUT2 is not showing a hardware list on Dingo, is that the background server is crashing.
From Everitts log:

I quickly tried to use Dingo edition 395, but at boot time with pfix=ram it compained that it could not find pup_395.sfs.
I had a quick look at Dingo from its command line shell and it is certainly using the new /dev/sd nodes for IDE drives, so that is quite a restructure, this must be what is triggering the bug in MUT2.
Also the mut client is not realising that the server connection is being dropped at an inappropriate moment, so this is another bug too.
You guys are great bug spotters! I'll fix these issues up at some point soon, I'm off to watch the motorcycle racing in Paeroa today, there might be some time tonight when I get back to fix up the bugs you spotted.

I've posted some updates that I managed to get done this weekend.
Some tweaks to cd drive ioctl (commands) useage.
Added in swapon/swapoff.

Has anyone out there that has an internal SD card (non-USB variety) found it accessible via MUT2? I don't have one to try with. MUT2 doesn't load the drivers for it at this stage, you'll have to do that manually.

Hi Wolf Pup,

Theres were a few cd-control command doubleups that weren't needed that I've removed in latest edition.
can you please check to see if audio pauses are fixed with mut2_1.0.0.1079?

Thanks,
Jesse

Jesse,

I tested your latest MUT (mut2_1.0.0.1079), and am happy to report the CD/DVD eject and close now work. One thing though, it seems to "double" the name of the drive (see pic below). The text runs over the ReScan button.

Hi JB,

That is odd.
Although theres a bit more data in the middle.

I figured it out. The revision ID is 8 bytes for your drive, and linux defines the revision right before the model.

struct hd_driveid {
...
unsigned char fw_rev[8]; /* 0 = not_specified */
unsigned char model[40]; /* 0 = not_specified */
...
}

And that way there is no nul string terminator to stop the string copy.
They probably did that so that all 8 bytes could be used for revision, and programs calling it, like mut, would be unlikely to crash with the apparently longer string.
I've fixed up mut, I'll post another revision in a day or so.

Hi Jesse,

[Sit Heel Speak]

I've noticed another quirk of Puppy 4's new treatment of hdxn partitions as sdxn: Sabayon Gentoo 1.1 PE, which also uses only sdxn, puts the SCSI drive at the top of the chain as sda. Dingo puts it at the bottom, on my system sdd. I don't know whether this is liable to get us into trouble or not.

(the above debug listing is from Puppy 2.17-1, wherein the scsi drive is sda)

Hi SHS,

Thats interesting.
The crash you reported has only been reported on Dingo editions so far. But for you it is happening on 2.17-1.
The only thing that is common with your system and the Dingo editions (that I am aware of) is that there is a scsi disk present.
So perhaps the bug in mut2 is related to scsi disk processing.
Putting Puppy edition aside, the crash bug seems to always happen when processing a scsi disk.
I'm not sure how to test that right at the moment, I'll think about it a little while maybe it'll come to me.

Hello,

I've posted a new update. 1.0.0.1109
Some tweaks to cd drive ioctl (commands) useage.
gui window position is saved/restored
Cd disk size added.
Fix hard disk fw revision (JB4x4 bug)
http://www.murga-linux.com/puppy/viewtopic.php?t=26336

All the cdrom controls are finally all working on my PC, be sure to let me know if you have any quirks.

Hello,

Ahem! I don't know how kosher this is, but here is mut looking just like pmount (left), running next to pmount (right), all in Dingo alpha 6, running on another computer I have that usually only gets to play DVDs.
This is mut2_1.0.0.1130, minor hacked pmount included.
The Pmount script is different!! please don't install it over your existing Pmount script, unless you make a backup etc... You'll need to put the mut file next to it if you do install it.
This should save the issues of installing tcl/tk for those Dingo testers.

SCSI disks work with this edition of mut2.
Floppy disks are still rattling about with 1130.

the mutclient frontend UI wiak idea rip

[Jesse]

Hi mcewanw,
Don't write off your idea already, pmount doesn't have eject buttons for the CDs, its doesn't have everything, neither does mut2s tcl/tk gui. If you check through the history of the two, there are elements of each that different people adore, perhaps there is a better soloution to gui out there that you can make happen?

I was getting the same errors as SHS but latest MUT2 (1.0.0.1130) working with LHP215.
Rebooted with LHP301 and working as well, except sda,b,c,d are now sde,f,g,h. Minor problem, as this means the 3 series is now usable for me.
And Pmount is detecting all drives for the first time. These are scsi2/scsi3 drives.

LHP215
