It would be better to update to the latest RELENG_6. Hangs on RELENG_6_1 is not so much interesting. For hanged RELENG_6 system, please do what described below and post the log of the ddb session. I'm not sure whether kbdmux was MFCed into RELENG_6 (AFAIR, yes). If you have it in your kernel, add the line hint.kbdmux.0.disabled=3D"1" into the /boot/device.hints to make ddb usable. After that, on the hang, enter ddb, and do ps and tr <pid> for all suspected processes. Better yet, add the following options to your kernel: options INVARIANTS options INVARIANT_SUPPORT options WITNESS options DEBUG_LOCKS options DEBUG_VFS_LOCKS options DIAGNOSTIC and, after hang, do in ddb show allpcpu show alllocks show lockedvnods ps For each process mentioned in show output, do where <pid> (for threaded processes, do thread <thread-id>; where). BTW, it would be great to add this instructions to the FAQ. --i0/AhcQY5QxfSsSZ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEhcfpC3+MBN1Mb4gRAty7AJ9iJHu1+humrXxq1ylFSNqMr4CKmACeP/tj s/syhnOvwXO8M5IJzUTsHI8= =m0DZ -----END PGP SIGNATURE----- --i0/AhcQY5QxfSsSZ--
