In Parallels, when Haiku(hrev28388) is running and i connect macbook embeded webcam (Parallels 'Devices' menu -> USB -> Built-in iSight), system freezes:

Is the USB controller by any chance sharing IRQs with another device in the system?

[aljen]

I think it would be Parallels Bridge (vendor: 1ab8, device: 1112) on IRQ 9, attaching syslog

[aljen]

eh can't attach file, trac error, syslog: ​http://hitomi.pl/haiku/syslog.txt

[luroh]

If the problem is still an issue on a recent revision of Haiku, are you able to get into KDL (Alt-PrtSc-D) and provide the output of the 'ints' command?

I'm going to close this. It's ancient, many things have been fixed in the meantime, IO-APICs might resolve this as well, there has been no feedback and the externally hosted syslog isn't available anymore either. Please reopen if this is still an issue and attach a fresh syslog and the suggested KDL ints output.
