Re: SiI3112 SATA controller problems - status

Søren,

The SATA seems better, but is still not working.  I tried the Oct 5 
snapshot, doing a clean install.  I CVSup'd and did
make buildworld
make buildkernel KERNCONF=GENERIC
make installkernel KERNCONF=GENERIC
reboot to single user
mount -a
swapon -a
mergemaster -p
make installworld

System has the same DMA write problems.  In this recent case it was 
installing termcap.  I tried the Oct 1 snapshot and it was the same, it 
errored in installworld installing tar.

The SATA is stabler as I can buildworld, but not stable enough to handle 
the installworld copies.

Here is what I copied from the console after it went into the debugger:
spec_getpages I/O Read failure(error=5)
vm_fault: pager read error
panic: initiate_write_inodeblock_ufs2: already started

Let me know if you want more information.  I will have to reinstall to get 
a dmesg, if you want a new one.

         -Derek
