[9fans] Hang at boot.

[9fans] Hang at boot.

[Jean-Baptiste Campesato]

Hello,
I installed Plan9 for three times and tested to boot with a floppy or Lilo.
And i always got a bug:
On startup I hung with this error : "status0 00000343" (Photo
http://www.a2lf.org/plan9/plan9.jpg) And the LED of the floppy stayed
lighted (Photo http://www.a2lf.org/plan9/floppylect.jpg).
Thanks for your help

The problem appears to be your Intel Gigabit ether card.
It may be as simple as adding support for the device id of your
card - looking at the source some cards are supported, some not
and yours is not listed; somone else on the list may be able to help more
or you could just experiment.

To get yourself going I suggest you swap the ether card for
an more boring 100Mb one, the wiki lists quite a few supported cards:

i'm not sure. the unexpected cls message should be benign and
i can't find anywhere in the kernel source where the following
'status0 00000343' could be coming from. but i just did some
greps, i might have missed something.

some left over debug I reckon

/sys/src/boot/pc/etherigbe.c:print("status0 %8.8uX\n", csr32r(ctlr, Status));

hmm. could be related to this in detach() which is called soon after that print:

	/* apparently needed on multi-GHz processors to avoid infinite loops */
	delay(1);
	while(csr32r(ctlr, Ctrl) & Devrst)
		;

we should probably time out the loops in there and return a failure value
instead of void.

it's /sys/src/boot/pc, not /sys/src/9/pc
hence the `loop 84740' after the cpu speed

status0 is always printed by the igbe boot driver on initialisation,
but it might not be at fault.

i'd suspect interrupts were getting lost and since 8086/24db is ATA,
it's mentioned in a pci routing message, and that's often fussy.
*nopcirouting won't work because boot ignores it.

you can probably ignore all that since i made the mistake of reading
my mail in time order and had not read the subsequent replies to the orginal question.

This reminds me, I have a small change to the NCR driver to address
exactly this type of irritant, best I submit them to patch.

PS: I note the patch/email command is not documented in patch(1).

Hello,
I'm not sure to understand (I'm French).
I must to calm down the Ghz from bios ? Or search a little Computer ?
Thanks.
