The following worked fine in 2.4.20. A pendrive formated as FAT32 with a
kernel and ramdisk loaded by syslinux. The start script loads usb-storage and
mounts the pendrive.
With 2.4.30 the system still loads the kernel and ramdisk but the start script
can no longer mount the pendrive, it gets I/O errors when it tries to. (see
dmesg output at end). If I remove the pendrive and re-insert it then the
mount succeeds.
The hardware is as follows 800MHz PIII on an i815 single board
computer, /proc/pci shows
