Mounting an ext3 partition

Description
I tested various versions of the 39924 nightly build on a Lenovo T61p laptop.
When mounting read-only an ext4 or ext3 partition with any gcc4 or gcc4 hybrid build I get a kernel panic. Trying the same thing with a gcc2 or gcc2 hybrid build works just fine.

It is recognized in DriveSetup, but it is an ext3 partition. Sorry, I should not have included the ext4 partition in my report, because that one is not recognized in DriveSetup.

Bummer :( Anyway if possible please include a photo of the kernel panic.

the ext2 addon provides its own DirectoryIterator, though the stack trace seems to imply the addon uses the DirectoryIterator provided by the kernel. It looks like a problem with the elf symbol resolution. Reassigning to kernel. Ingo maybe has an idea.

Replying to diver:
Is it recognized in DriveSetup? My ext4 partition is not. Should I open a ticket for that korli?
It's probably normal as we still miss a few features. Don't hold your breath, but they should be included by the end of January.

Ah, indeed, I missed that. All kernel classes (at least all with virtual methods) should live in an appropriate namespace (the unnamed namespace for classes only used within a source file or BPrivate or B* for others) to avoid clashes with equally named classes in add-ons. In this case the problem is the DirectoryIterator class in device_manager/legacy_drivers.cpp.

I added a LegacyDrivers namespace for legacy_drivers.cpp in hrev39945.

Awesome! I can mount my ext4 partition since hrev40129. Thank you very much!
You're welcome. Please test a bit, just be warned that data corruption is possible when mounting read/write.
