So, no, you can't boot from the hard drive and read files off the CD from the loader. However, you can copy the kernel and mfsroot off of the CD and stick them in /boot/new/kernel and /boot/new/mfsroot.gz and then manually load the new kernel and mfsroot from the hard disk's loader to get into the installer. I.e. something like: ok unload all ok load /boot/new/kernel ok load -t mfs_root /boot/new/mfsroot ok boot -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You can read about more of the gritty details here: http://people.freebsd.org/~jhb/papers/bsdcan/2007/ You might be able to shuffle some IRQs around using 'hw.pciX.Y.INTA.irq' tunables. Probably you have a device driver whose interrupt handler isn't handling some condition. I would suspect ata as it's interrupt handler is rather simplistic with no chipset-specific hooks, and I've seen several reports of interrupt storms with ata(4) recently. > Thx, > Scott > > > On Tue, Sep 16, 2008 at 7:12 AM, Gary Jennejohn > <[EMAIL PROTECTED]>wrote: > > > On Mon, 15 Sep 2008 22:57:38 -0700 > > "Scott Gasch" <[EMAIL PROTECTED]> wrote: > > > > > Hi, > > > > > > I'm running freebsd 7.0-RELEASE-p4 on a 4-core amd64 box.

Gah, wrong tunables. These devices are on PCI link devices, so you'd need to do something like 'hw.pci.LNKA.irq' (where LNKA is the name of the link device in the ACPI namespace). Verbose boot messages (boot -v) can tell you which link device you PCI devices are using. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You will get a BTX fault in 7.0 if your CPU does not support 64-bit "long mode" (i.e., amd64). You can check to see if your CPU does support it by looking in the 'AMD features' line of 'dmesg' from an i386 kernel and seeing if you have a 'LM' feature. If you don't, your CPU only supports i386. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Some drivers don't work with PAE (see all the 'nodevice' lines in /sys/i386/conf/PAE). You'll need to purge those drivers from your config.

GPT booting works just fine on 6.x and later. Using the gpt(8) utility you basically do: # gpt create foo0 # gpt boot foo0 The second command creates a special boot partition in /dev/foo0p1. You can then add partitions: # gpt add -t ufs foo0 # newfs /dev/foo0p2 gpart(8) in HEAD works similarly.

My understanding is that a GPT requires the MBR to be a PMBR (only one partition in the 4th slot with a special type of 0xee that covers the whole disk). What this box is doing is trying to make the MBR match the first 4 partitions in the GPT. I'm not sure if you will be able to get FreeBSD's GPT stuff to recognize that reliably. Marcel (cc'd) might have some ideas. If you can get FreeBSD's GPT support to handle this disk it will mean that you will have to use only GPT device names (so /dev/ad0p4a instead of /dev/ad0s4a). You will also need to make sure the GPT partition for FreeBSD has the right UUID since your partition contains a BSD label. > [EMAIL PROTECTED] ~]$ sudo gpt show ad0 > gpt show: unable to open device 'ad0': Operation not permitted > > > >Normally with GPT you don't put a BSD label inside > > a GPT partition, so you wouldn't have /dev/ad0p4a, but instead would use a > > separate GPT partition for each filesystem/swap/etc. The fstab from my > > laptop (not a macbook) looks like this: > > > > # DeviceMountpoint FStype Options Dump Pass# > > /dev/ad0p3 noneswapsw 0 0 > > /dev/ad0p2 / ufs rw 1 1 > > /dev/ad0p5 /tmpufs rw 2 2 > > /dev/ad0p6 /usrufs rw 2 2 > > /dev/ad0p4 /varufs rw 2 2 > > /dev/acd0 /cdrom cd9660 ro,noauto 0 0 > > > > Are you booting using boot camp or parallels or some such? > > Yes, I think It's the problem.

Hmm, so the set of ps output you have from DDB shows a lot of runnable processes and swi6 (Giant taskq) as the only running thread (all consistent with your hang).

It would be really helpful if we could get a crashdump, though I realize that may not be doable. Otherwise, full DDB ps output from a hang would be a good start. Primarily I would want to see what the system is doing and why it isn't running the threads on the run queue. It might also be useful to add KTR_SCHED tracing so we can get the output of that via 'show ktr' from DDB when it hangs. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Do you see memory allocation errors in netstat -m? Specifically this line: 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) If so, it may be that the IPoIB layer has an mbuf leak.

You probably have the other GPT paritions already mounted via another name which removes the names in /dev/gptid. Try booting an install CD or USB stick such that you use an alternate root fs and don't mount any of the partitions on your drive. Then you should be able to see the entries in /dev/gptid and update your fstab appropriately. If you console access you could also try to update your fstab to use /dev/gptid/ directly instead of /dev/XXXpYY and reboot. If it works I believe the /dev/XXXpYY names will now be gone from /dev and the /dev/gptid names present instead. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

You can register a hook for the 'mountroot' EVENTHANDLER event which will fire after / is mounted. (You could compare rootvnode against NULL during module startup to determine if you should defer your work to the EVENTHANDLER vs doing it right away.) If you need to wait for all local filesystems to be mounted, then you will need to have some userland utility poke your module via a sysctl/ioctl/etc. after the filesystems are mounted (you could use a custom rc.d script for this). -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

There is a problem in the kernel that causes with 3 or more processors (including logical CPUs from HTT). Disabling HTT in the BIOS is probably your best bet as it will get you down to 2 CPUs which should work much better. HTT also isn't but so useful anyways for most workloads.

Maybe add some debug info to devclass_set_driver() to print out the previous driver's name (and maybe the value of the pointer) before free'ing the softc.

By default proc0 gets a hard limit (lim_max vs lim_cur) of MAXDSIZ, and the max limit is what the ELF image activator in the kernel uses when figuring out where to mmap the runtime linker: /* * We load the dynamic linker where a userland call * to mmap(0, ...) would put it. The rationale behind this * calculation is that it leaves room for the heap to grow to * its maximum allowed size. */ addr = round_page((vm_offset_t)imgp->proc->p_vmspace->vm_daddr + lim_max(imgp->proc, RLIMIT_DATA)); > The second aspect also counters this assumption, for machines that have less > than or equal to > 1 GB memory, and setting the MAXDISZ = the maximum memory size will not > cause such problem. > For example, if the physical memory size is 512 MB, and setting > MAXDSIZ=(512*1024*1024) > will not cause this problem.

Umm, the amount of physical memory has no bearing on how the virtual address space for userland is laid out. Do you know what virtual memory is and how it works? Your first e-mail seems to contradict this paragraph as in your first e-mail you noted that the physical memory doesn't matter, the solution was to not raise MAXDSIZ higher than 1GB and that is consistent with running out of virtual address space due to MAXDSIZ reserving too much address space for malloc(). -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Also, if you are running FreeBSD/amd64 and running a 32-bit binary under freebsd32 emulation, then it has 4GB of VA space rather than 3GB, so you can give it more MAXDSIZ. It's really up to the user to only use a maxdsiz that works. You can also adjust the hard limit before exec'ing a process that needs a smaller dsize and leave MAXDSIZ larger for other processes. Since it is dependent on things the compiler can't know about at the build time of the kernel, we just let the user set it to whatever and if they set it too high things break until they lower it. You can even set this at boot time via 'kern.maxdsiz' tunable in the loader w/o needing to recompile. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

GPT was defined along with EFI, so many folks assume that you have to use EFI to boot a GPT-labelled disk. However, FreeBSD has its own BIOS-based bootstrap that can handle GPT-labelled disks.

The full DMESG can be > viewed here: http://jago.pp.fi/temp/dmesg.txt You can ignore them. FreeBSD creates two psuedo-devices on x86 called apic0 and ram0. Their sole job is to reserve the memory ranges used by APIC devices and system RAM to prevent those address ranges being reused by anything else (such as PCI BARs). Many systems also reserve those ranges as a system resource via ACPI (or PnPBIOS for the non-ACPI case). What is happening is that the ACPI system resource driver isn't able to reserve these ranges because they are already claimed by apic0 and ram0. The important point is that some device claims them. It doesn't really matter which one does. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Having an autoreport check if memtest was run before it reports, or having it only run with -CURRENTmight be useful. That's not quite true. Many hardware failure-type panics look the same (a machine check exception panic, an NMI due to a hardware error (this has a unique panic message), or panics in pmap_remove*() on x86 cover the vast majority of them).

Yes, your feeling is correct. This sort of race is inherent to NFS if you do not use some sort of locking protocol to resolve the race. The infinite retries sound like a client-side issue. Have you been able to try a newer OS version on a client to see if it still causes the same behavior? -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

I can confirm that ZFS's FHTOVP() method never returns ESTALE. Perhaps this
patch would fix it? It changes zfs_fhtovp() to return ESTALE if the
generation count doesn't match. If this doesn't help, you can try changing
some of the other return cases in this function to ESTALE (many use EINVAL)
until you find the one that matches this condition.

So the odd thing here is that ffs_fhtovp() doesn't return ESTALE if VFS_VGET()
(which calls ffs_vget()) fails, it only returns ESTALE if the generation count
doesn't matter.

Yes, and note that the chipset has set a register to indicate a RAM parity error as well, so it is not a random NMI. Have you checked your BIOS' event log?

This problem makes kernel debugging, panic analysis, and > other console-oriented viewing basically impossible. I was recently going to look at it. The somewhat drastic approach I was going to take was to add a simple serializing lock around trap_fatal() and a few other places that do similar block prints (e.g. mca_log()). One of the issues with fixing this in printf itself is that you'd want probably want to serialize complete lines of text on a per-thread basis. You would want to be able to accumulate this line of text across multiple calls to printf (think of it as line-buffering ala stdio). However, some folks may be nervous about printf not printing things immediately. The other issue is that lots of code assumes it can call printf from anywhere and everywhere. Mostly this just means that if you add locking and line- buffering to printf(9) you have to be very careful to make sure it works in odd places. Probably a lot of this could be solved by deferring things like trap_fatal() until panic() has already been called (which is bde's preferred solution I think). -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Both, the xAPIC is mostly backwards compatible. The extension of the ID field just uses bits that are reserved (and hard-wired to 0) on the older APICs.

What version of FreeBSD are you using and what > do you need help doing? From the subject line, I imagine Jack is using 6.3-STABLE and wants to backport the driver from 7.0 to 6.3. Backporting most drivers from 7.0 to 6.x isn't a big deal (can generally just copy over and compile). However, zyd(4) is a wireless driver and the net80211 wireless networking stack is quite different in 6.x vs 7.0, so that is where it would be complicated to backport the driver. I'm not intimately familiar with net80211 in either branch, so I'm unsure how much work the backport would be. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Use /boot/loader rather than /boot/kernel/kernel at the boot2 prompt. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
