I've been seeing the following message when booting up my 164SX, right after the timecounters are set: Stack backtrace: db_print_backtrace() at db_print_backtrace+0x18 backtrace() at backtrace+0x2c sched_switch() at sched_switch+0xf4 mi_switch() at mi_switch+0x1fc cv_wait() at cv_wait+0x260 _sema_wait() at _sema_wait+0x8c ata_queue_request() at ata_queue_request+0x2b4 ata_getparam() at ata_getparam+0xd8 ata_identify_devices() at ata_identify_devices+0x78 ata_boot_attach() at ata_boot_attach+0x58 run_interrupt_driven_config_hooks() at run_interrupt_driven_config_hooks+0x30 mi_startup() at mi_startup+0x144 locorestart() at locorestart+0x64 --- root of call graph --- This is using a yesterday's tree (as pulled from the Greek cvsup mirror -- cvsup.gr.freebsd.org). I buildworld'ed and buildkernel'ed on 5.2.1-RC2 and then rebooted to my brand-new -CURRENT kernel. The kernel config (GATEKEEPER) is a GENERIC without all the extra stuff not available or needed in my SX (e.g. eisa, usb, extra nic's and scsi controllers, inet6, nfs, etc.). I didn't notice the above message when I first booted the new kernel (since the whole process was done remotely), so I went on with my usual "buildworld revisited" procedure (as a stress test for the new kernel), which finished just fine. I did notice, however, that system load was around 3 throughout the buildworld, which is kinda weird (I've never seen anything above ~1.20 when building world on -RELENG). I attach the output of dmesg and sysctl for this kernel, plus a dmesg of my -RC2 kernel and of a 'boot -v' of the -CURRENT kernel. More weird stuff ahead; intuition says that the backtrace should also appear in the dmesg of the verbose'd boot-up, right? Ummm... Nope. No sign of a backtrace there. Any ideas? Note that a buildworld on my oldish pca56 takes about 6-6:30 hours, so if this backtrace stuff was something lethal, it would have fired up during this time (I guess). Could this be another spurious ata problem (as the backtrace seems to suggest)? \n\n -- Nikos "Noth" Ntarmos | < ntarmos at ceid dot upatras dot gr > NetCINS Lab. @ C.E.I.D. | [ http://{noth,p2p}.ceid.upatras.gr/ ] U. of Patras - Greece | ( 38.2594N, 21.7428E ) ( 1024D / CF95160A ) --jI8keyz6grp/JLjh Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="dmesg.current" Copyright (c) 1992-2004 The FreeBSD Project.
