Well guys, I tried upgrading one of my older machines today to the
latest 4.0. It was running an older 4.0 kernel (Nov 29 1999).
I've included the dmesg output from the (successfully booting) older
kernel at the end.
The newer kernel locks up in several ways:
* First, it locks up with process 0 stuck in 'atawait' while
trying to scan the CDRom on the second IDE bus. This is after
it has successfully scanned the hard drive on the first IDE bus.
* Second, if I remove the 'ata1' config entry it gets past the
initial ata probe but then locks up in 'conifhk' which is in
the run_interrupt_driven_config_hooks() procedure
in kern/subr_autoconf.c
It locks up here after printing 'waiting 15 seconds for SCSI devices
to settle'. Several minutes later it's still waiting :-(.
* If I remove the second ata device AND I remove the SCSI devices
and controllers so it detects no SCSI devices, it gets all the
way to where it says "Mounting root on wd0s4a", then gets an error 6,
then says "Mounting root on wd0a", then just stops. Breaking into
DDB and doing a ps shows 'init' and 'sh' both blocked in 'wait'.
The hard drive appears to work -- panic does sync the disks.
* The second time I did this when I CTL-ALT-ESC'd into DDB I suddenly
got a whole bunch of console startup output. I 'cont'd from DDB,
and nothing... CTL-ALT-ESC'd into DDB and got some more console
output from the normal startup sequence before it gave me the DDB
prompt. 'cont'd. nothing.
I got it to the point where ping works but nothing else does.
HEEEEELP! Whats happening!!! :-( :-( :-(
At the moment I am stymied. I switched to a GENERIC kernel and got the
same results, so it isn't anything weird that I have done in my own
kernel config.
I was hoping that someone would have an idea.
