2.6.8.1 doesn't boot on x86_64

2.6.8.1 doesn't boot on x86_64

[Tigran Aivazian]

Hello,

I haven't heard about it on x86_64 discuss list so I thought it is worth 
asking if someone else has encountered this. When I boot 2.6.8.1 kernel 
(patched with kdb) the last thing I see is:

Freeing unused kernel memory: 160k f

I don't get the whole word "freed", only the first letter "f". This is SMP 
kernel. I will try recompiling without kdb and also booting as "nosmp" to 
see if it makes any difference.

Fedora Core 2 smp kernel boots fine, btw.

Kind regards
Tigran

booting with nosmp panics dereferencing NULL pointer and the stack trace 
(ignoring offsets) looks like this:

sysfs_hash_and_remove
sysfs_remove_link
class_device_dev_unlink
class_device_del
class_device_unregister
scsi_remove_host
ata_host_remove
ata_device_add
ata_pci_init_one
piix_init_one
pci_device_probe_static
__pci_device_probe
bus_match
driver_attach
bus_add_driver
driver_register
pci_register_driver
piix_init
child_rip

Btw, in this context I noticed something interesting earlier (with Fedora 
Core 2 kernels) --- if I plug in the second SATA disk to the 3 
channel then Linux only detects the first SATA disk and the second host 
thread just exists. I didn't know if it's a bug or expected behaviour so I 
just plugged in the second SATA disk into the first controller so I get 
sda and sdb disks and everything works fine (with FC2 kernel, not 
2.6.8.1).

I cc'd Jeff Garzik as the functions on the stack (ata bits) seem to belong
to his area. Jeff, this is booting 2.6.8.1 with "nosmp" on an x86_64 with
two SATA disks (sda and sdb). Booting without "nosmp" hangs as described
below. Booting with "nosmp" panics as described above.

Kind regards
Tigran

I have now reverted kdb patches and the system boots fine, both as smp and
as nosmp. The kdb patches which I applied to 2.6.8.1 were:

kdb-v4.4-2.6.8-common-1.bz2
kdb-v4.4-2.6.8-x86-64-1.bz2

downloaded from oss.sgi.com. It may still be a problem with base kernel 
which kdb just triggered --- who knows...

Kind regards

Ok, thank you, but what would be even more interesting is if someone
running Intel EM64T machine with ICH6 and 2 SATA disks on ata1 and nothing
on ata2 also confirmed that 2.6.8.1-smp kernel works for them...

Kind regards

2.6.8.1 works fine for me on lots of different boxes.

Have you tried without the kdb patch? 

If not I would suggest to enable earlyprintk and see if you can
get better output.

FWIW, a non-kdb patched 2.6.8.1 kernel runs fine on a dual CPU box
(Tyan Thunder K8W with 2x Opteron 242):

Linux zebigbos 2.6.8.1 #1 SMP Fri Sep 10 18:57:48 CEST 2004 x86_64 unknown
