Just had a panic on an amd64 laptop running netbsd-7 as on 7th Jan. System was running a wildfly-8 java server, firefox browser, postgresql, (idle) mysql and a few xterms. Using the intel DRMKMS driver with NoAccel.
panic below - I appear to have a netbsd.0.core.gz & netbsd.0.gz panic: kernel diagnostic assertion "uvmexp.swpgonly + npages <= uvmexp.swpginuse " failed: file "/opt/netbsd/7/sys/uvm/uvm_pager.c", line 472 cpu0: BAegRiNnI NtGr: aScPeLb aNcOkT .LO.W.E RED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 vpanic() at WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 netbsd:vpanic+0x13c uvm_fault(0xfffffe81f2ba75d8, 0x0, 2) -> e fatal page fault in supervisor mode trap type 6 code 2 rip ffffffff80a78b01 cs 8 rflags 10202 cr2 8 ilevel 8 rsp fff ffe8064358b08 curlwp 0xfffffe8064590860 pid 7919.5 lowest kstack 0xfffffe80643552c0 kern_assert() at netbsd:kern_assert+0x4f uvm_aio_aiodone_pages() at netbsd:uvm_aio_aiodone_pages+0x51b uvm_aio_aiodone() at netbsd:uvm_aio_aiodone+0x89 workqueue_worker() at netbsd:workqueue_worker+0x89 cpu0: End traceback...
