Hey, at least I didn't > cross-post to questions, stable, scsi, and current! :) Ok, sounds good, just checking. :) Can you provide the output of mptable for this box? In the SMP case, -current does interrupt routing for PCI interrupts a bit differently, which might be a possible reason. Hmm, but you are getting interrupts eventually it seems. > I guess my next step is to try and trace through what's happening - > can you suggest a good place to start (like a routine to start > tracing), or is there anything I can do that might get more info for > the people that know what is going on? Actuually, KTR is your friend here. :) Read the ktr(4) manpage, then compile a kernel with KTR_MASK and KTR_COMPILE set to KTR_INTR|KTR_PROC. Then when it hangs, break into DDB and look at the longs via 'show ktr' to see if you can locate any interrutps coming in from ahc0 or ahc1. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
