A problem with NFS version 3 mounts on big endian machines (m68k, sparc

<p>
|
|
|
|
<li id="bootargv">
|
|
<strong>020: FUNCTIONALITY FIX</strong><br>
|
|
The kernel was using a fixed and hard-coded location for the arguments
|
|
vector passed from the <b>/boot</b> loader. This prevented
|
|
<b>/boot</b> from placing the boot arguments vector at any
|
|
other location, causing a kernel crash early in the autoconfiguration
|
|
stage. In 2.5, the bootblocks will be modified to use a new location.
|
|
Hence, if you wish old kernels to boot on a new bootblock, those
|
|
kernels will only work if they were linked with this patch.

<li id="installboot">

i386 installboot had a sign extension bug which prevented proper bootblock

|
initialization when the root filesystem was placed beyond 4GB.

<p>
|
|
|
|
<li id="hme">
|
|
<strong>023: DRIVER FIX</strong><br>
|
|
The sparc hme(4) and be(4) drivers work poorly on some types of SS-20
|
|
machines. This is because those machines lie, saying they support 64-bit DMA
|
|
bursting. No sun4m machines support that.

The Xhp as shipped does not have the execute permissions set. The fix is
