Thanks a lot, SUMITANI-san! Yes, this fixes panic and even 'halt -p' works as expected. 'zzz' command works too, but machine never come back from the suspend mode (looks like interrupt controller programmed incorrectly or something like this). -- Boris Popov http://www.butya.kz/~bp/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

SMP + APM = panic -> fixed!
Hi, We're having this problem for long time (from the old 4.0-CURRENT days), but Mr. SUMITANI discovered a bug and fixed it. The problem was that we got worng gdt pointer for the current cpu, then panic... The followings is a patch to fix the problem. Thanks a lot, SUMITANI-san! Please test this and I'll commit & MFC this if we have no problem with this fix. I love to have APM enabled SMP system with 4.1-RELEASE.

SMP & APM
Hi, Has anyone tried having APM and SMP in the same kernel? It panic()'s mine :) Basically the machine panics a few seconds after I do 'apmconf -e'. apm seems to return normal values though. I've attached a sample output from APM, dmesg and my kernel config. I get a trap 12: page fault in kernel mode mp_lock = 0109; cpuid = 1; lapic.id = 0100 fault virtual address = 0x75f0 fault code = supervisor read, page not present interrupt pointer = 0x8:0xc0208a4c stack pointer = 0x10:0xff80dd78 frame pointer = 0x10:0xff80dd7c code segment = base 0x0, limit 0xf, type 0x1b DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle interrupt mask =<- SMP: XXX Also, nm kernel.debug | sort shows that 0xc0208a4c is in Xbpt --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum Copyright (c) 1992-1999 The FreeBSD Project.
