since august 8th, 2003 the kernel on my i386 pentiumIII won't compile. the problem arises in locore.s with the definition of the constants $PAGE_SHIFT and $PTESHIFT used in `shr' and `shl' instructions within the macros `fillkpt' and `fillkptphys'. i've tried to cvsup(1) RELENG_4 and RELENG_4_8 every day for over a week now, but kernel builds (as part of a buildworld) don'...

...te it if someone can forward this to the appropriate place. On Netbsd 5.1, if you turn off DDB in the kernel config file, XEN domain0 will not build due to an unresolved symbol, cpu_Debugger. The fix is pretty trivial: (sorry, I didn''t include a diff) on line 925 of sys/arch/amd64/amd64/locore.S, change from #ifdef XEN /* XXX debug code */ to #if defined(XEN) && defined(DDB) /* XXX debug code */ BTW, tuning the kernel to removed unused drivers and options reduces size from 13meg to 5meg, along with correspondingly faster boot times. --Dean ____________________________...

As promised, the updated if_xl with full busdma support / other improvements has been MFC'd to 4.8-stable. While I have put this driver through extensive testing, it is possible that there may be bugs which are either present in the -current version or that I added in the MFC process. So, if you cvsup to -stable anytime in the future and notice problems with if_xl, please tell me ASAP!

I was looking at the Sparc 64 4.7 or 4.8 port, wondering if its in any state to put on my Solaris v100. Just need the basics, eide, network, kbm,mouse, graphics (x). A bonus would be support for the lom (light out management) features and the flash card. Reason for change is I HOPE that the math (ssl) performance is better on FBSD, as well as I am just tired of keeping track of

Hi all Does FreeBSD support a non-executable stack on any of the tier 1 and 2 platforms that has this feature? If not, are there any plans of implementing this and is there a patch I can use for 6.0 (when it is released)? Best regards db

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
