I deleted this discussion before I hit this panic:
uid 0 on /usr: file system full
panic: pool_get(vmmpepl): free list modified: magic=3a62b60; page 0x3a62000; ite
m addr 0x3a63574
i4b-L1-isic_isac_exir_hdlr: EXIRQ Rx Frame Overflow
call_sicallback: 289 more dynamic structures 297 total
syncing disks... 49 49 45 26 13 3 3 3 panic: remrunqueue
the interupt problems are probably cause by the softint being blocked, while
the hard interupts schedule soft ints...
Now, this kernel contains trickle sync, but not softdep. Which file
needs to be up-to-date?
