[parisc-linux] Problems compiling LVM

[Helge Deller]

Hi Torsten,

The problem is that your userspace program tries to do a direct 16 or 32-bit 
read- or write-access to address 0x40067cf3 - which lies on a "unaligned 
address" (e.g. not a a 32-bit boundary). 
On Intel architectures this fault is automatically handled by the hardware, 
while you get an unaligned access trap on parisc.

The first parisc-kernel which should handle this trap correctly is 2.4.0-pa39 
(in CVS), so I would encourage you to update your kernel.

Greetings,
Helge
