Can't boot installer: integer divide fault
[Please CC me as I am a stable user and not on the -current list] I'm running stable on a box at home and wanted to check if the -current kernel fixed a problem with my CD-RW drive. So I downloaded the boot floppies from current.freebsd.org, the 20010419 snap (which John B. tells me installs OK on his system). I disabled nearly everything from the visual config, then quit from that. It got as far as PnP detection then failed with an integer divide fault. The following was on the screen (copied by hand!): sio0: configured irq 4 not in bitmap of probed irqs 0 sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 8250 sio1: configured irq 3 not in bitmap of probed irqs 0 vga0: Generic ISA VGA at port 0x3c0-0x3df iomem 0xa-0xb on isa0 unknown: PNP0303 can't assign resources unknown: PNP0f13 can't assign resources fatal trap 18: integer divide fault while in kernel mode instruction pointer = 0x8:0xc03085f5 stack pointer = 0x10:0xc080671c frame pointer = 0x10:0xc0806768 code segment= base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor flags = Interrupts enabled, IOPL = 0 current process = 0 (swapper) trap number = 18 panic: integer divide fault I've attached a dmesg from a verbose boot of 4.3 on the same hardware.

Re: Install kernel gets divide overflow
Weird, I installed the April 19 snap here locally on a testbox without any problems. Rgr, I'll try Apr 19th and send another note with some debug info if it is still dying. To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message
Install kernel gets divide overflow
[please CC replies; I'm not on the -current list] I'm trying to boot a -CURRENT kernel to confirm it really does fix a problem with my hardware (see kern/26046). I've tried a couple of snapshots from current.freeebsd.org between 1st the 15th April. None has booted. Each dies with an integer divide trap after (during?) PnP processing. (This is booting the install floppies, not after an install). Is this a) a known problem that will be fixed sometime soon, so just keep trying occasionally b) a big surprise to all concerned and deserving of further investigation, starting with the output from boot -v ?

Re: cpp change breaks ipfw
#define addr 192.186.2.5 #define mask 255.255.240.0 #define rule(ADDR,MASK) add pass tcp from ADDR ## : ## MASK to any 25 setup rule(addr,mask) This is a well-known artifact of the ANSI C rules. You need to do two levels of macro in order to get the macro args expanded in the paste operator: #define addr 1.2.3.4 #define mask 255.255.255.0 #define hn(A,M) A ## : ## M #define rule(A,M) add pass tcp from hn(A,M) to any 25 setup rule(addr, mask) which produces add pass tcp from 1.2.3.4:255.255.255.0 to any 25 setup when fed through an ANSI preprocessor (i.e. not "gcc -E" and not /usr/bin/cpp on 3.x!). This also works if (e.g.) addr is defined on the command line. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Re: btokup().. patch to STYLE(9) (fwd)
I seem to remember there once was a comment in a well-known body of code, which went something like: You are not supposed to understand this. It was (IIRC) the process switching magic at the heart of fork() in V7 (and earlier, I assume).

Re: SOFTUPDATES hangs keyboard
I've just done my first CVSup since the 3-Stable split, using RELENG_3. This was after Matt D. committed a couple of VM fixes back to the 3-S branch. I have also enabled 32-bit DMA on my drive at the same time (amazing what you can learn from reading LINT - and read speed went from 3Mb/s to 12Mb/s). Whatever it was, it has seemingly fixed the problem I was having with softupdates-related system hangs. Previously, if I enabled softupdates on /usr/src, it would hang within a few seconds doing cd /usr/src/games; make. Now I have done two entire make buildworlds with /usr/src and /usr/obj on the same softupdates partition with no hangs. It's still not perfect, because every so often when I reboot I get something like syncing disks: 13 9 4 4 4 4 4 4 4 4 4 4 4 4 4 giving up and I have had a panic when shutting down (something about freeing vnodes). I'm now running with DDB and INVARIANTS so I'll try and catch something more useful. And I'll try removing the flags from wd0 in the kernel and see if that is the problem Greg, still not quite brave enough to run softupdates on /usr or /var To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message
WD/ide_pci bug! [was Re: SOFTUPDATES hangs keyboard ]
Well stone the bloody crows. System: HP Kayak XA 440BX M/b, P-II, Quantum Fireball ex4.3a For months I've been running with no flags on either wdc0 or wd0. Having followed the recent discussions about DMA mode etc I looked at LINT and added flags 0xa0ff to wd0. Rebuilt the system using the latest 3-Stable code, including Matt D.s VM fixes, and tried yet again the test that has quite reliably frozen my system (softupdates enabled on /usr/src, cd /usr/src/games, make) and, lo and behold, it worked. I thought it was probably Matt's VM patches but (just to make sure) I built a kernel without the wd flags and tried again. It failed. This seems to be saying the problem is the WD driver: When I have flags on my disk, it all works; when I use the default, it fails (but only on filesystems with softupdates activity...) Any ide_pci experts like me to try some more tests? Matt: I'm sorry I ever doubted the VM code or the softupdates!

What's wrong with us.unix.kbd? This also swaps a bunch of other things - Grave-Esc, BS-Del, etc. It was more confusing, so I made a new keymap. To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message
