Kernal Panic "failed to acquire spinlock for a long time” in _user_poll

Kernel Panic (64bit) on 2011 MBP (*Dual Core H/T i7, 8GB, 500GB hdd)

I recently installed Haiku 64 on my 2011 MBP. I have suppressed Intel graphics drivers (using Vesa) but everything else is pretty-well default per installation.

I am experiencing constant kernel panic tantrums, to the point that I had trouble running os/app package updates and installing larger programs through the package manager. I suspect this may have to do with the Broadcom ethernet driver as I am usually doing something network related when the machine keels over, and the longest it has stayed up is when the ethernet was physically disconnected.

A (sorry blurry) screen shot is at: ​https://discuss.haiku-os.org/t/haiku-on-mac/8815/67?u=bronzie94 and attached

See if disabling SMP makes any difference.

I disabled 3 of the 4 logical cores using the “Pulse” demo app. (If I try to load the Haiku boot mgt screen with “space bar” at boot, In order to disable SMP there, the machine just sits on a grey screen. Doing this does seem to cause it to load a previous snapshot, but I can’t see any options and need to power cycle the machine to proceed).

Within a minute of opening Otter Browser, and opening the Youtube homepage, the machine kernel panicked when I started typing in the search box.

Att 3: MBP Devices listing including Broadcom Ethernet detail

I am now pretty confident that the problem relates to Ethernet - I disconnected the ethernet cable and played Hexen 2 for over 30 mins, also playing with screen settings etc. In between I used the devices app to grab screenshot Att 3, and also brought up a few other small apps, played with them and closed them.

I then used WebPositive to browse the BeBook and User Guide for 15+ minutes - the machine is still happily running now...

Att 5: random unattended) General Protection Exception - Tracker Task Loop

.... and who knows, there is likely more going on than just Ethernet. I returned to the machine after a spell, and Att 5‘s lovely Kernel Panic was waiting for me. (General Protection Exception - Tracker Task Loop).

UPDATE

After my next boot, fully sans ethernet cable, I copied about 6 GB of data from a thumb drive over USB to the hard drive; spent hours playing games in DOSbox and Scumm VM; Playing mpg, h264 and HEVC videos with the media player from the HDD (both while DOS box was running and separately) - the machine was rock-solid stable and has not had an app crash let-alone a Kernel Panic through that whole process. Ethernet driver or related kernel issues seem strongly indicated :)

Please try with a nightly build and see if anything different occurs.

[bronzie94]

Done - Running hrev54446 x86_64 now - seems more stable on the Ethernet front. Have had a different kind of kernel panic, but not the type I posted here. Will run for a few more hours and see what happens. So far Haiku Depot hasn’t Kernel Panicked me and software installation is proceeding :)

Please attach that different kind of kernel panic.

[bronzie94]

Seems to be resolved under hrev54459 - I have been using the computer, with normal day-to-day ethernet activities, solidly for over a day without issues. interestingly Otter browser crashes out under the last three nightlies I have been using - cannot launch without a crash. Will report that separately.

:)

Please attach that different kind of kernel panic.

Cannot reproduce under current nightlies - must have resolved :)

Thanks all

Seems very strange it would be resolved, unless it was HDA-related... let's leave this open a while longer and see if it returns.

[bronzie94]

Cool - I will report if it happens again :)

Assume fixed.
