Hi all I've builded my oe using bitbake. I try to run it in a mini2440 from an sd cart. During boot proses I take the following errors: Starting udevudevd version 124 started udevd[742]: main: the kernel does not support inotify, udevd can't monitor rules file changes ------------------------------------------------------ Remounting root file system... uncorrectable error : end_request: I/O error, dev mtdblock4, sector 0 Buffer I/O error on device mtdblock4, logical block 0 end_request: I/O error, dev mtdblock4, sector 8 Buffer I/O error on device mtdblock4, logical block 1 uncorrectable error : end_request: I/O error, dev mtdblock4, sector 16 Buffer I/O error on device mtdblock4, logical block 2 uncorrectable error : uncorrectable error : end_request: I/O error, dev mtdblock4, sector 24 Buffer I/O error on device mtdblock4, logical block 3 uncorrectable error : end_request: I/O error, dev mtdblock4, sector 0 Buffer I/O error on device mtdblock4, logical block 0 uncorrectable error : end_request: I/O error, dev mtdblock0, sector 0 Buffer I/O error on device mtdblock0, logical block 0 end_request: I/O error, dev mtdblock0, sector 8 Buffer I/O error on device mtdblock0, logical block 1 uncorrectable error : end_request: I/O error, dev mtdblock0, sector 16 Buffer I/O error on device mtdblock0, logical block 2 uncorrectable error : uncorrectable error : end_request: I/O error, dev mtdblock0, sector 24 Buffer I/O error on device mtdblock0, logical block 3 uncorrectable error : end_request: I/O error, dev mtdblock0, sector 0 Buffer I/O error on device mtdblock0, logical block 0 Unknown HZ value! (80) Assume 100. EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended ALSA: Restoring mixer settings... ------------------------------------------------------ It finally boots in command line. So anybody knows?: How important these errors are? Why do they appear? Are they a possible reason why I don't have gui? ps I run the same image in 2 different sd-carts and the problem exists in both.
