Hi, I have a Ultra 10 which I network boot in a diskless configuration to run FreeBSD. This weekend I downloaded 6.0-BETA1 and got that set up. I've gotten the following panic reproduceably while trying to compile the lang/perl5.8 port when the machine starts to swap. Note that this is typed in from looking at the console (I'd need to set up a serial console) so apologies for any typos. panic: bstrategy: no bufobj bp=0xc3dee258 cpuid = 0 KDB: enter: panic [thread pid 7 tid 100027 ] Stopped at kdb_enter+0x3c: ta %xcc, 1 db> trace Tracing pid 7 tid 100027 td 0xfffff80017df84c0 panic() at panic+0x16c swapdev_strategy() at swapdev_strategy+0x70 swp_pager_strategy() at swp_page_strategy+0x8c swap_pager_putpages() at swap_pager_putpages+0x3e8 default_pager_putpages() at default_pager_putpages+0x1c vm_pageout_flush() at vm_pageout_flush+0x14c vm_pageout_clean() at vm_pageout_clean+0x334 vm_pageout_scan() at vm_pageout_scan+0x738 vm_pageout() at vm_pageout+0x3e8 fork_exit() at fork_exit+0x94 fork_trampoline() at fork_trampoline+0x8 db> Please let me know if you want anything else examined from the debugger. The server is an x86 box running FreeBSD 4.11-STABLE: FreeBSD misty.eyesbeyond.com 4.11-STABLE FreeBSD 4.11-STABLE #0: Thu Apr 7 10:51:05 MDT 2005 glewis@misty.eyesbeyond.com:/usr/src/sys/compile/MISTY i386 I created the swap file on the server as follows: dd if=/dev/zero of=swap bs=4k count=128k The fstab entry looks like: /swap none swap sw 0 0 Note that the last time I tried this was with FreeBSD 5.2 and a similar setup worked then. The machine has been off since then for various reasons and I thought now was a good time to resurrect it so I could unbreak the x11-wm/afterstep-stable port on sparc64 :). -- Greg Lewis Email : glewis@eyesbeyond.com Eyes Beyond Web : http://www.eyesbeyond.com Information Technology FreeBSD : glewis@FreeBSD.org
