Parport + PPA = EXT2-fs panic

In both kernel 2.1.32 ( patched for parport ) and 2.1.33 everytime I use
/dev/sda4 ( ppa ) I get kernel panics. Below are part of the log file
showing how the various drivers interact. I can reboot, e2fsck the
disk, start again and the same thing happens. If I go back to 2.1.29
with parbus-1.18 ( hand built, i.e. not part of the kernel ), then
everything works fine. ( Hmm ?? )

Note: I even tried using the parbus-1.18 package with 2.1.32, and had
the same problem. I think it must be a change in the kernel and not in
the parbus/parport stuff. - Note the line below saying:
