It occurs only when trying to shutdown the box: | Waiting (max 60 seconds) for system process `vnlru' to stop...done | Waiting (max 60 seconds) for system process `bufdaemon' to stop...done | Waiting (max 60 seconds) for system process `syncer' to stop... | Syncing disks, vnodes remaining...2 2 0 0 done | All buffers synced. | Uptime: 8d2h4m58s | NMI ISA 30, EISA 0 | NMI ISA 20, EISA 0 | NMI ... going to debugger | NMI ... going to debugger | NMI ISA 20, EISA 0 | NMI ISA 30, EISA 0 | NMI ... going to debugger | NMI ... going to debugger | NMI ISA 20, EISA 0 ... | timeout stopping cpus | [ thread pid 11 tid 100016 ] | Stopped at acpi_cpu_c1+0x6: leave | db> timeout stopping cpus | timeout stopping cpus | [ thread pid 11 tid 100015 ] | Stopped at acpi_cpu_c1+0x6: leave | db> timeout stopping cpus | timeout stopping cpus Once these are displayed, a power cycle is required to recover. Shutdown sometimes works, and sometimes not. DDB prompt does not work because it does not accept entered characters properly. And, this symptom seems not specific to stable/9. This may be a hardware specific issue, but where should I start to debug this from? -- Hiroki ----Security_Multipart(Sat_Jul_27_13_06_41_2013_678)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (FreeBSD) iEYEABECAAYFAlHzR1EACgkQTyzT2CeTzy3K7gCeMR5BBWTULotF10UmNg6AhD9K KdcAoKTkdRDEWrpyOCFMdd1aTtluRGYq =AK9z -----END PGP SIGNATURE----- ----Security_Multipart(Sat_Jul_27_13_06_41_2013_678)----
