[9fans] "new" 9load freezes

["Nils O. Selåsdal"]

Hi, I've a box that used to work before the kernel/9load(realmode ?)
changes late last year. Copied 9load and kernel as of yesterday to
/n/9fat, and after this:

MBR...PBS...Plan 9 from Bell Labs
ELCR: 0A00
apm ax=f000 cx=f000 dx=40 di=ffff ebx=4b0e esi=-1
dev A0 port 1F0 config 427A capabilities 2F00 mwdma 0407
dev A0 port 170 config 05CA capabilities 2F00 mwdma 0007 udma 0407
dev B0 port 170 config 85C0 capabilities 0F00 mwdma 0407
ether#0: elnk3: port 0x300 irq 10: 00608cf5ade3
#l0: status 0xFFFF, diag 0xFFF

nothing more happens. Any more info I can provide ?
A CD (from yesterday) boots fine.

If you boot from CD, draw a new window, and run

	9fat:
	ls -l /n/9fat/9load

does 9load have the al bits set in its mode?

It didn't. Now it has (chmod +al /n/9fat/9LOAD)
but same result.

That last line should have read '
#l0: status 0xFFFF, diag 0xFFFF
Which comes from etherelnk3.c. I removed that, and some
other ether drivers from 9load, now it works !

did you ls -l /n/9fat/9load after doing the chmod?
try reformatting your 9fat.  i'm sure the problem is
that your 9load isn't contiguous on disk.

Yes. Checked and double checked this.
Even repeated the procedure again after it failed to boot,
to no avail.

Ok. The new 3 things I did when it worked this last time
was remove 2 backup kernels I had on 9fat and copy back
the kernel I wanted to use. Perhaps that did some reorganizing
required before I copied over the (now much smaller) 9load

Will test again with the recent 9load binary on sources, but
not today.

There's an error in that driver or in a new kernel with that driver in
it, I'm not sure what it is.  In the absence of an etherlink card, it
behaves itself, so it can't be too difficult to isolate.  I have all
the history I thought I might need to isolate it, but I haven't yet
attacked the problem in all earnestness.

What did you do about the network?
