Hmm, well, I finally got my first actual system panic which wasn't obviously caused by my own screwing around. On the console I have:
free inode /usr/cvs/net/64 had 0 blocks panic: Negative bio_offset (-19038208) on bio 0xce51be28 cpuid = 0; lapic.id = 01000000 Debugger("panic") Stopped at Debugger+0x55: xchgl %ebx,in_Debugger.0 If I type 'trace' at that point, i get a long traceback which is more than I can stand to type in right now (I'm typing this on my Mac, while looking at the console of my FreeBSD machine). But based on that, it looks like it just did a syscall(136) -> mkdir -> kern_mkdir -> ufs_vnoperate -> ufs_mkdir -> vput -> ufs_inactive -> ffs_truncate -> softdep_setup_freeblocks -> handle_workitem_freeblocks -> ffs_blkfree -> bread -> breadn -> spec_vnoperate -> spec_specstrategy -> spec_xstrategy -> g_dev_strategy(ce51be28,0,c139258,4,ce51be28) at g_dev_strategy+0x87 I then typed 'panic', thinking that should get me a dump somewhere. But, well, I don't see it... This may be easy for me to recreate. What I did was I had just deleted three UFS partitions and replaced them with two UFS2 partitions. One of the two UFS2 partitions was mounted at /usr/cvs/net, and I had done a tar-pipe to copy all of /usr/cvs/net-old (a directory) to /usr/cvs/net. After the reboot I had: (257) cd /usr/cvs (358) du -sk net* 1415362 net 2225480 net-old (note: I have background_fsck="NO" in /etc/rc.conf) This probably isn't as helpful as it could be, but of course this happened just went I wanted to rush out the door. Let me know if I should try to recreate it, and what to do if I get another panic. This is on a dual-processor machine, -current as of Jan 27th. Dual Althon 2000. 512meg RAM. For some reason, /var/run/dmesg.boot is just a single line right now: d2s3d: SIZE=512 MTIME=Jan 2 19:34 2003 (CLEARED) but presumably I can get a more useful one by rebooting again... -- Garance Alistair Drosehn = [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Institute or [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
