AMD64 FreeBSD 12.0-CURRENT #1 r333269: Sat May 5 11:47:44 UTC 2018
While compiling lang/rust
panic: Bad link elm 0xfffff8042e7cf40 prev->next != elm
cpuid = 1
time = 1525606495
KDB: stack backtrace:
vm_pqbatch_process_page() + 0x276

vm_fault_hold() + 0x1d12
(See attached photo for more)
On reboot into single-user, fsck -p reports a lot of "Incorrect size N -> 0" and "Link count 2->1" and says the FS is fine, but a fsck without -p finds numerous files to reattach to lost+found, most of which look like temp files from the lang/rust compilation.
Filesystem in question is UFS+SU+Trim, bsize=32k, fsize=4k
No kernel dump available unfortunately.
Time out my own old ticket, the issue has not resurfaced or gotten any attention.
