It also seems to work fine with a normal kernel with interrupt threads on the alpha. I have one last bug to track down (we are grabbing shed_lock with interrupts disabled at some point late in the sysinit right before init forks, probably the first time we grab the sched_lock). Currently my running kernel is hacking around it by always assuming the saved ipl in a spin mutex is ALPHA_PSL_IPL_0. :-P Once I track this last bug down I'll update the alpha.ithreads.patch so you all can test it and help fine other bugs. We also are still in need of some low-level PCI interrupt enable/disable code for two of the PCI chipsets. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
