At boot, ubuntu can't recover from corrupted ext4 filesystem

[max]

System description:
The system where the error occurred uses a CF card as hard drive, formatted as ext4. The motherboard (fujitsu ds2703-s) supports CF cards as hard drives, and the card is detected as an IDE device.
During boot, the filesystem was marked as corrupt, and instead of correcting the affected inodes, the kernel issued an error trying to mount the device.

The kernel could not mount filesystem, so the error log was lost. I copied the error code that was shown on the Call Trace:

Code: 00 55 89 e5 57 89 c7 56 53 e8 f3 68 26 00 8b 5f 04 b8 ff ff ff ff 8b 77 08 eb 1c 8d b6 00 00 00 00 8b 0c 85 80 56 81 c0 8b 57 14 <8b> 14 0a

From the Call Trace it seems the error was during a system call to mount the device.
