I reproduced the very same crash today with:
4.3-STABLE FreeBSD 4.3-STABLE #2: Tue May 1 20:28:53 CEST 2001
I have a make world on a freshly-cvsupped source tree in progess right
now, in the hope that it will relieve the problem.

Could this be due to using a /stand/sysinstall from an old release on a -stable system where world and kernel have been updated? -- Thomas Quinot ** Département Informatique & Réseaux ** quinot@inf.enst.fr ENST // 46 rue Barrault // 75634 PARIS CEDEX 13 Thomas,
It could be, I don't know. It's been a while since I've seen this
problem myself. I'm running 4.3-STABLE without any problems now.

After makeing kernel and world and recompiling sysinstall from a freshly-cvsupped source tree, I still get a panic right after the 'probing devices' message. Excerpts from kgdb session follow. If any other system information or any further forensics are necessary, please feel free to ask. :) I am very intrigued by this crash dump. Why dp can be NULL at this point is beyond my understanding. Thomas.

I was able to recreate a similar crash when trying to mount a CD, but the crash dump was of no help (the stack frame pointer was apparently wrong, and gdb was unable to produce a backtrace). However, I noted that these crashes occur only when one specific faulty disc is present in the CD burner at boot time (a failed disc that was not fixated correctly). When this CD is in the drive at boot time, I get the following messages: (cd0:sym0:0:2:0): got CAM status 0x4c (cd0:sym0:0:2:0): fatal error, failed to attach to device (cd0:sym0:0:2:0): lost device (cd0:sym0:0:2:0): removing device entry When the CD is not in the drive at boot time, I get no such error, and sysinstall and mounting a CD work correctly afterward. Hope this helps, Thomas. -- Thomas.Quinot@Cuivre.FR.EU.ORG Responsible Changed From-To: freebsd-bugs->dd I have a patch to fix this. State Changed From-To: open->closed fix applied to -current, thanks for the report. |
