iprowifi3945 driver completely hangs the system

[jackburton]

Since some revisions, Haiku hangs at boot on my machine, unless I remove that driver. The system is so hanged that it won't enter KDL.

As I suspected: I removed the network drivers, and added back one by one with net_server running. As soon as I add the iprowifi3945, the system hangs. Syslog follows.

"Since some revisions" could mean since the WLAN drivers were added to the image. You could try to boot with those disabled/removed.

Unless you have already done that, you should wait a while (maybe one or two minutes) after the hang. If it's some spinlock deadlock/double lock, the system should panic after a while.

Finally, in case not all of the syslog is written to disk, you could "Enable debug syslog" in the boot loader and reenter the boot loader after resetting machine after the hang and "Display syslog from previous session" (both in the "Select debug options" submenu).

Oh, sorry, I overlooked your first comment.

It's likely to be an interrupt storm. You could have a look at the "ints" KDL command.

For example, I had this problem on my laptop after having installed openSUSE - the machine would randomly assign IRQs to the ethernet and wireless cards.

I would, if I could enter KDL :-)

For example, I had this problem on my laptop after having installed openSUSE - the machine would randomly assign IRQs to the ethernet and wireless cards.

Last week, when I opened ticket #5548, I tried the ints KDL command, and I remember the wireless card was sharing IRQ with at least 4 or 5 other devices.

"ints" KDL command, without wireless. I remember wireless gets mapped at irq 10

I added a picture which shows (besides that the screen of my laptop needs cleaning) the output of "ints" KDL command, after having removed the offending driver (since with it, I can't even enter KDL).
