Hello, I am back with more information. The machine had been up mostly idle for about 1 1/2 hours again. I am starting to suspect that it is being idle that may also trip the wire here... maybe, given my 128megs of RAM and 300 megs of swap, that's when my computer decides that it's time to swap some stuff and boom. Alfred's patch indeed seems to have changed things a bit: It paniced after 1h37m uptime during a CVS checkout, with the following: panic: sleeping with vm_mtx held trace: Debugger panic msleep swap_pager_getpages vm_fault1 vm_fault trap_pfault trap calltrap ---trap 0xc, eip= 0x2824dc2e, esp=0xbfbfe16c, ebp=0xbfbfe160 then after 'c': syncing disks... panic: mutex vm owned at ../../kern/vfs_bio:2998 nice long trace: Debugger panic _mtx_assert vfs_busy_pages bwrite vfs_bio_awrite spec_fsync spec_vnoperate ffs_sync sync boot panic msleep swap_pager_getpages vm_fault1 vm_fault trap_pfault trap calltrap and again the same trap message like above. After hitting 'c', it freezes at the dumping: resetting devices part. This starts to become interesting... will follow up with more when found. -- Regards: Szilveszter ADAM Szeged University Szeged Hungary To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
