I've had this problem since I've migrated to FreeBSD 7 from 6. FreeBSD 6 never seemed to have any problems. As FreeBSD Stable is a continuous development, you have good chances to narrow down the culprit by bisecting. The assumption is, one single SVN commit broke your functionality and you just have to find out which one. Get sources from SVN, then switch to the earliest Stable/7 to confirm your assumption (it broke with 7). If it works, check out a few thousand SVN revisions later, try again. If it doesn't work, switch to an earlier revision, a late Stable/6. Each step cuts the number of SVN revisions in question in half, after some 10 or 12 iterations you're down to a single revision. Having a single revision pretty much directly points you to what the problem is. This helps developers very much and with some luck you can reverse-apply this change to a more recent set of the sources. Thanks for the idea! is downgrading possible or will I have to reinstall? Downgrading is possible. make buildkernel, make buildworld, etc. MarKus - - - - - - - - - - - - - - - - - - - Dipl. Ing.

Re: fun with if_re
Am 04.02.2009 um 10:05 schrieb Gerrit Kühn: After the last update (11th December 2008) I have noticed the following strange behaviour on at least two machines (identical hard- and software): After weeks of flawless operation, the network connection on both interfaces suddenly starts to mangle packages. Even a simple ping can show up to 50% or so package loss. The machine is mostly unreachable via net. ifconfig up/down did not cure this, turning off checksum-offloading and stuff did not help. Even simply rebooting the machine did not make the problem go away! I had to power-cycle them by unplugging all cables to get back to normal operation. I've seen a similar, but fully reproducible behavior on this ethernet hardware. It turned out to be not a problem of the driver: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=kern/130957 Is it possible to use if_re from head as drop-in replacement to test the patches available after 12/09? The other way, using an older if_re, worked by replacing sys/dev/re/ if_re.c, sys/pci/if_rlreg.h and sys/pci/if_rl.c, so the answer ist likely yes. MarKus - - - - - - - - - - - - - - - - - - - Dipl.

Re: Unhappy Xorg upgrade
Am 30.01.2009 um 10:16 schrieb S.N.Grigoriev: after upgrading to Xorg 7.4 from the FreebSD ports tree I've got my USB stack completely unusable. If Xorg is started (manually or via xdm) my USB printer and external HDD become unreachable (timeouts). It is not enough to kill Xorg to restore the USB functionality. FreeBSD has to be restarted. I use FreeBSD 7.1-STABLE (amd64) compiled from fresh sources. Any tips? One way is to look for patches in the PR database and simply try them, for example: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=kern/130957 (shameless plug) This could help you and, if you find something helpful, add a chance to get a PR fixed.

Re: recently happend kernel panics regarding usb
Am 25.01.2009 um 11:12 schrieb Oliver Lehmann: I'm experiencing recently happend kernel panics while making bacula backups on my external USB harddisk. It first happened some days ago while I was running 6.4-PRERLEASE. I then updated to 6.4-STABLE and enabled all the kernel debugging stuff. Looking at your screenshots, I'm getting plenty of these g_vfs_done() = 5 errors with an ordinary pen drive on various stages of stable/7 as well. The pen drive works flawlessly on other computers. Same for another pen drive I tried for verification. If you throw the EHCI driver out of the kernel your drive will use either OHCI or UHCI (both are slow). This seems to help, at least for the limited things I use this pen drive now. The good thing is, you obviously had a FreeBSD installation which worked fine with USB 2.0 drives. This would be a good starting point for the search of a fix. Any chance you can get back to that state? If the panics appeared without any change on the system, could you stress test this drive a little on another computer? MarKus - - - - - - - - - - - - - - - - - - - Dipl. Ing.
