Hello, 

My system hangs shortly after I logged in Gnome desktop. SysRq-W shows
that a bunch of task are blocked in "D" state, they seem to wait for
some I/O completion. I can try to hand-copy some data if requested.

I found these messages in dmesg:

~$ grep -C2 end_request dmesg-2.6.24-rc3-mm1 
EXT3-fs: mounted filesystem with ordered data mode.

lp0: using parport0 (interrupt-driven).

These errors occur *only* with 2.6.24-rc3-mm1, they are 100% reproducible.
2.6.24-rc3 and 2.6.24-rc2-mm1 are fine.

Maybe something is broken in pata_via driver ?
