Linux/Alpha kernel compiled with egcs-19980721 causes "oops" in shutdown

[Michal Jaegermann <michal at ellpspace dot math dot ualberta dot ca>]

Linux kernel compiled on Alpha with a help of egcs-19980721 snapshot
seems to boot and run without any special problems but in a shutdown
sequence creates a series of faults.  It is always the same and it
looks like that:

 rpc.mountd(247): Oops 0
 ....
 rpc.nfsd(256): Oops 0
 ....
 inetd(225): Oops 0
 ....
 inetd(225): Oops 0
 ....
 lpd(236): Oops 0
 ....
 portmap(214): Oops 0
 ....

Reasons recorded in log files are always the same:

 Unable to handle kernel paging request at virtual address 0000000000000020

This behaviour is consistent for 2.0.33 and 2.0.35 kernels compiled for
Alpha EB64+.  The same kernels recompiled with 1.0.3a egcs release do
not exhibit such behaviour.

This, from what I know, may be a bug in Linux kernel sources but
something did change between 1.0.3a and the current sources.
Snapshot I used was configured with './configure --enable-haifa';
for 1.0.3a only default setting were used.  The snapshot definitely
has some optimizer bugs, as I reported yesterday.
