soft power and power light on 712/60

Hello,

I have sort of a weird problem. I installed Debian 3.0 on Sunday and it = came up great on my 712/60. The only problem is the soft-power switch do= esn't work and the power light flashes while searching for the boot devic= e and then goes off once it starts booting. =20

Output of uname -a:
Linux gecko 2.4.20-32 #1 Sat Mar 22 14:03:22 CET 2003 parisc unknown and /proc/sys/kernel/soft-power =3D 1

The only thing unusual about the setup is that I replaced the old 500mb H= P hard drive with a 4.5gig IBM drive with a 68pin-50pin converter.

Is the drive and converter causing the problem, or is there something I c= an do software wise to fix this?

Thanks,
Derek Ellis

Hmm it is highly probable.

Four years ago, for a project of upgrade 712 workstation, we asked to HP if it was possible to put internal (SE) 4Gb disk. HP said that it was only supported on 712/100.

Later, I had the opportunity to test Linux on a old 4Gb (SE) external disk with an old 712/60. (Even thought it was the very begining, it still works fine and help me a lot). Then I remember that 'not supported' didn' t means that it would not works. So I removed this disk from its enclosure and put it into the workstation. Well it works but not for a long time: apparently it warmed too much but fortunately not too long time (so I can put it back in its original enclosure and continu to work). So there are an actual problem of heat exchange in this small box?

For above mentioned project, we also use external SE 4Gb disk with wide (68 pins) connector without pb. Is your 4.5Gb IBM disk is well of SE type?

I don't know about the light, but a kernel upgrade might help the switch. Earlier kernels did not enable the power switch. Not sure which version made it work (although I thought the kernel on the Debian 3.0 CDs supported it.) I haven't had a chance to run parisc linux for a while, unfortunately, and the D270 I was using did nothing when the power switch was switched, although the kernel I was running was supposed to enable it, so maybe the kernel doesn't enable it for all parisc machines? (The switch did work in HPUX and I think it even worked at some point in Linux and later stopped.)

I've got a problem similar to yours with my 712-60 using 2.4.20-pa32 precompiled. The power light while searching for a suitable boot media (as it should), then goes on as expected. The power switch does not work. With earlier kernels (say 2.4.9-something) it worked. Any advice on that ?

I had a similar problem a while ago. The following URL should lead you to the discussion I had that time:
http://lists.parisc-linux.org/hypermail/parisc-linux/8454.html
So eventually, the soft power worked, and is still working on my 712/60 even with the latest kernel. Please note that I build the kernels myself, I never use prebuilt ones (unless for installing ;) ). You should find my working .config as an attachment
(http://lists.parisc-linux.org/hypermail/parisc-linux/att-8454/02-.config).
You can use this one, or do a diff with your .config to see what you're missing.

Hope this helps.

Kenneth
