Bug #1277

Updated by tuxillo about 9 years ago

Using HEAD from Feb 1, 2009 I got 
 
 temporary freeze, ~1 minute, and then panic. 

 

 This SMP (w/ APIC_IO) kernel on UP host. 

 

 Freeze happens when accessing file with UFS filesystem 
 
 (for vkernel), just after output when fsck finishes: 
 
 vnconfig -cs labels vn0 FILE 
 
 fsck -y FILE 
 
 mount /dev/vn0s0a /mnt 

 

 I have seen this panic a few times; 
 
 not every time script w/ commands run. 

 

 Crash dump uploaded to leaf as *.41.
