 |
|
Supermount runs ok in my system with gentoo-dev-sources-2.6.0-r2. Today I've update to gentoo-dev-sources-2.6.1 (using the same .config)and when I boot I got this:
| Code: |

I know its a problem in supermount, if I compile the kernel without support it everything runs fine. |

I got the same problem. But see it first on gentoo-dev-sources-2.6.0-rc2

I am also getting this problem, unfortunately. I guess it's not just me, then  |

Me as well. Additionally I could not shutdown or reboot the PC since either of those commands caused the usual "The system is going down for reboot now" messages, but it just sat there... I don't know if that's related to this bug or not.
I've filed a bug report here, I'm still a bit new to reporting bugs though. |

Me too, supermount doesn't works... An the battery too on 2.6.1 kerel!
With 2.6.0 everything works ... I'm starting to think that this 2.6.1 it's not really a good kernel...

I've been having the exact same issues! I didn't see any other posts until this one, glad (well kinda) I'm not alone.
Does .1 offer anything that would make it not worth using the .0 sources instead?
Oh, and I've also noticed that it doesn't cause problems if supermount is compiled in the kernel, only if I actually use it in fstab. Seems like the problem is when it's used, not just when it's compiled. |

I was having that problem as well, but after two reboots while I was configuring stuff it suddenly doesn't give me the errors on boot up or the shut down problem, but supermount still isn't working. |

I started having the same problem when I updated to gentoo-dev-source-2.6.1. I've noticed that the problem goes away if you omit the ",--," part and everything after that in the options. So I changed my fstab from:
| Code: | | none /mnt/cdrom supermount fs=iso9660:hfsplus,dev=/dev/cdroms/cdrom0,--,ro 0 0 |
to
| Code: | | none /mnt/cdrom supermount fs=iso9660:hfsplus,dev=/dev/cdroms/cdrom0 0 0 |
And the problem seems to have gone away. The disadvantage, of course, is that you cannot give options to the filesystem itself, but I can live with that for now.
Another problem I've noticed is that if I specify fs=auto, I get the following in dmesg: | Code: | | request_module: failed /sbin/modprobe -- auto. error = 256 |
If I simply leave the "fs=" part out, it defaults to "auto" and it works OK. It also works as shown above, manually specifying FS types. |

the kernel 2.6.1 "oops" issue went away with the closure of bug 37807... but supermount still doesn't work right if you use "auto" as a fs= option.
in order to get rid of this second nuisance, you either manualy specify filesystem to be mounted by supermount (e.g. for cdrom/dvd you would probably use: fs=udf:iso9660) or upgrade to gentoo-dev-sources-2.6.2_rc1, which already includes the new supermount-2.0.4 patch.
