Notice some lines in the syslog complaining about ATA and more than one DMA mode.

Did previous builds boot, and if so can you narrow down the revision where it broke?

in reply to:  2 comment:3 by Anarchos, 14 years ago

R1alpha2 boots. It broke 3 months ago. I will try to narrow the latest working one.

comment:4 by idefix, 14 years ago

I experience the same problem when booting Haiku from an 11 year old laptop harddisk (IBM DKLA-24320).
Once I tried to narrow it down, but got frustrated because sometimes (~1 in 10) the same release would boot without any problem. I therefore suspect a race-condition somewhere...

Replying to anevilyak:

I've narrowed it down to somewhere between hrev38099 and hrev38307. Unfortunately there weren't any nightlies created between those changesets.

comment:6 by idefix, 14 years ago

Component: - General → Kits/Storage Kit
Owner: changed from nobody to axeld

It looks like changeset:38235 is the culprit.

hrev38234 (+hrev38237 to fix the build) boots fine, while hrev38235 (+hrev38237&hrev38238 to fix the build) freezes.

comment:7 by stippi, 14 years ago

If this changeset is indeed the problem, then you should still be able to enter KDL and get a stack trace of all the media_addon_server and input_server threads (both use the code in question). Use teams to get a list of all teams, then threads <id of media_addon_server> then bt <each thread id in turn>. The stack traces should reveal a deadlock.

Replying to stippi:

KDL (Alt+Print+D) doesn't work. KDL appears if to pull out a flash card only.

So are all the latest build (gcc 2, 4, 2/4, 4/2)

comment:10 by idefix, 14 years ago

You can't enter KDL with the keyboard, but I never tried to enter it by pulling out a flashcard. Will try that trick next.

I think the problem happens when the input-server starts and wants to take control of the keyboard, because Haiku freezes approximately at the time that the numlock-led on the keyboard should turn off.

comment:11 by stippi, 14 years ago

Ok, so maybe it's the input_server which locks up. You could pull out that flash card and still get the back traces of the input_server threads once in KDL, like I described above. You probably have to take photos and attach them here. Thanks in advance and sorry for the hassle.

comment:12 by idefix, 14 years ago

It doesn't KDL when I pull out a flashcard; probably because I don't boot off a flashcard, but off a slow HD. I therefore tried the nest best thing: cut off the power to the HD. However, this wouldn't lead to KDL when the system was fully freezed, as there wasn't any HD-activity. So I had to cut the power just before that moment, while hmulti_audio.media_addon was scanning /dev/audio/hmulti/. Is there a way to enter KDL via the serial port?

Thanks a lot, so it's indeed the input_server dead-locking, and you provided just the info needed! I don't know when I'll have time to fix this, but I'll try to do so ASAP.

Replying to idefix:

Is there a way to enter KDL via the serial port?

No. In such a case one can add something like 

(sleep 10; kernel_debugger) &`

at a strategic place in the boot script, though.

comment:15 by idefix, 14 years ago

That's a much more civilized way of getting into KDL.

Using this technique, I could get the stack-traces when the system was completely frozen. I've attached them for completeness' sake: input_server_st.txt​, media_addon_server_st.txt​

Maybe it is related to my irq5 assigned to a lot of devices : ​http://imagebin.org/126227

comment:18 by stippi, 14 years ago

No, no. I am pretty sure I've understood the problem and am going to commit a patch which hopefully fixes the problem after I've done some testing. Incidentally it also fixes some other potential concurrency problems in add-on handling in the input_server.

Resolution: → fixed

Problem should be fixed in hrev39741 and hrev39742. Please reopen if not.

Blocking: 6819 added

(In #6819) I am marking this as duplicate. If hrev39741 and hrev39742 don't fix the problem, please re-open the ticket. The "dodgyness" you were observing is actually expected by the nature of the bug that was fixed. The lock-up happened depending on the timing with which input devices appeared in the system during the input_server initialization phase.

comment:21 by Anarchos, 14 years ago

It worked for me.
Thanks a lot to idefix for spotting the faulting changeset, and stippi for this so fast and efficient solution !! I could not imagine to get back haiku booting on hard drive and usb key within this week end :)

Really, we have experienced and first class developpers in Haiku.
