I recently upgraded a 4.11-REL machine to 6.0-REL and have run into some
snags. While the installation from CD went fine, after configuring and
enabling my ed0 NIC, bad things start to happen.
FWIW, this machine is an ancient (hardware circa 1991, BIOS circa 1994)
dual-Pentium 133 MHz machine, with EISA/PCI and onboard SCSI.
So far I can reliably reproduce two panics, one appears to be a ed driver
bug (based on reports of similar panics with different NICs, notably nge)
and one is a filesystem corruption problem.
Here's the process that I go through to reliably reproduce both problems.
1) Boot machine in multi-user mode
2) After ifconfig ed0, machine panics with a trap 12 in ithread_loop.
3) In debugger, reset (or panic to get vmcore)
4) Reboot in multi-user mode, but set "hint.ed.0.disabled=1" in the boot
loader (to avoid ifconifg panic)
5) Root filesystem is fsckd; all other filesystems are scheduled for
background fsck
6) Encounter panic "ffs_valloc: dup alloc"
7) In debugger, reset (or panic to get vmcore)
Attached is the full dmesg and stacktrace output from kgdb for the *second*
panic, since I figure this is the more critical issue.
