Boot hangs on rocket during broadcom43xx "media change"

[umccullough]

On my Dell Inspiron B130, the boot started hanging on the rocket icon starting with hrev46236. When I enable debug output, I see that it's during a broadcom43xx "media change" event.

I have tested on the latest rev and it's still broken.

I can get a syslog and listdev output from hrev46235 if desired. Laptop has no serial port.

[umccullough]

Oops, I guess i wasn't paying attention, it was actually broadcom43xx.

Which means this is actually a wifi chip.

Disabling it with the bootloader blacklist feature allows the boot to proceed.

Hardware-specific issue with known and documented workaround, moving out of alpha5 milestone.

I also have this issue on my old ASUS laptop. It currently has hrev44295 which boots without any problem. We tried to upgrade it at RMLL last week and it hanged as documented here.

[mmu_man]

You said your laptop doesn't have a serial port. Does it have a parallel port? If so it should be possible to use a laplink cable to debug it. I'm not sure if it's still available by default though.

[mmu_man]

Ok, I've been checking some revisions according to the git log of both broadcom43xx and the freebsd_wlan stuff...

hrev45433 boots hrev45453 boots as well hrev46104 boots also hrev46271 doesn't boot

The only broadcom43xx-related change in this interval is a trivial looking renaming of allocation flags... so I suppose it's probably in the freebsd_wlan or freebsd_network stuff.

Reading again the summary I suppose the problem appeared in hrev46236, or I misunderstood?

Please try with TRACE_DRIVER enabled at ​http://cgit.haiku-os.org/haiku/tree/src/libs/compat/freebsd_network/driver.c?id=fc3b9496eb2a64bf81d3abfbd551caa2e6866a2f#n31

I've enabled trace in driver.c as directed, recompiled the broadcom43xx driver, placed it in system/non-packaged/add-ons/... bin/ and the link to it in ...dev/net/

Blacklisted the system copy... and the syslog shows that it's booting from the non-packaged copy. So I would think I should be seeing the trace enabled driver output?

This is the debug log output I see when booting from that copy of the driver and seeing the lock-up.

(See attached image)

Please try a current nightly.

[mmu_man]

I just updated my old asus to the nightly and unblacklisted the driver, but it seems it doesn't find its firmware so it doesn't go as far as checking for media change:

[mmu_man]

Ok, after running install-wifi-firmwares.sh and rebooting…

pagefault in bwi_getradiocaps(). :-(

[mmu_man]

Ok, it seems that bwi_attach calls bwi_getradiocaps before the ic_softc field is set (it's reset just after in the code, but I suppose the BSD kernel does it beforehand at some point), causing a NULL dereference.

[mmu_man]

Fixing it seems to get us back to the original behaviour: hanging at loading the driver. I'll have a look.

[mmu_man]

So, after managing to use my antique laplink cable to get seri… hmmm… parallel debug output, I get this from the driver:

Ok, found a nasty bug in our compat layer… >:-)

[waddlesplash]

Well, that's a separate issue; please open another ticket and I can take a look at that. :)
