Hang during boot: intrepid 2.6.27-3 hp pavilion

[gpk]

Binary package hint: linux-image

On a dual-core AMD laptop (an HP Pavilion G6062EA), Intrepid hangs during boot. Not quite completely, though. You can hit <enter> or <esc> and it staggers on for a while. After about 13 keypresses, it does eventually finish booting. It then runs nicely (except that X is messed up...).

The behaviour is the same with "noapic" and/or "noapictimer" . This is a regression relative to 8.04, as it booted very nicely then. Both now and then, you need "noapic" to get the USB to work. (That's another bug, but a pretty standard one, these days.)

I attach /var/log/syslog . You can see where I hit <enter> by the several-second jumps in the time.

I attach /var/log/syslog from a boot with default parameters (e,g. "ro").

...actually with "noapic" and "noapictimer", it does boot. It gets up to the point of
"configuring network interfaces" and then hangs there, but eventually (after about 1 minute)
something times out and the boot proceeds. Again, neither of these arguments was needed
for 8.041 .

I attach that /var/log/syslog here

By the way, this is an entirely current version of intrepid, installed from alpha-5 and
updated/upgraded this evening.

Incidentally, it hangs on shutdown. Some mixture of <enter> <esc> and waiting seems to be necessary.
It takes at least a minute or two to turn off.

[gpk (gpk-kochanski)]

Here's the /var/log/syslog for a boot with "noapic" . Again, we get lots of hangs, and if you pound the keyboard enough, it eventually boots.

[gpk (gpk-kochanski)]

Incidentally, sometimes you needed to hit <esc>. <enter> was not always enough to shake it loose. Perhaps that's a clue.

---------------

Here's the /var/log/syslog from a boot with "noapictimer" . It does boot, but there is a long hang at "configuring network interfaces". Didn't need this flag before with 8.041.

Here's the result of lspci -vv

The system is intrepid, updated to a couple of hours ago. It was installed from an intrepid alpha-5 CD, then upgraded via aptitude.

Isn't it the same bug as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/263782 ?

gpk, make a test with Stefan's kernel...

[gpk (gpk-kochanski)]

It's probably not the same bug. I get no screen corruption, and unlike 263782,
booting with noapictimer almost solves the problem. Also, I see no intermittency:
the boot process is exactly the same every time. (I've done at least a dozen
boots with "noapic" and at least 6 or 7 with "noapictimer".

I'll test with stefan's kernel ASAP, though.

Hi gpk,

This actually sounds more like bug 254668. Please take a look let us know. Stefan is also working with the bug reporters there. Thanks.

[gpk (gpk-kochanski)]

Problem still exists in Beta version with 2.6.27-7 kernel.

Actually, it does not seem to be 254688. (Or, so Stefan Bader concluded.)
The problem there doesn't respond to noapictimer, while my problem does.

No luck. I download it, then
sudo dpkg -i linux-image-2.6.27-3-generic_2.6.27-3.3smb5_amd64.deb
then boot with the 2.6.27-3 kernel found in grub's menu, and I still need to keep
hitting keys.

[Leandro Pereira de Lima e Silva (leandro-limaesilva)]

Same problem here, 2.6.27-7 still has it in release candidate.

mismo problema!

same problem! mexican user with a hp pavilion dv6951la notebook!
ubuntu 8.10 64 bits

[Sheldon (leewsb)]

I have the same problem. I have a dv9618ca (dv9500) and I have exactly the same problem. However, I found that if you boot with pci=noacpi it boots and works fine.
