I've gotten a "Panic: vm_bounce_page_free: invalid bound buffer" every 
few days since I installed FreeBSD 2.0-RELEASE.  My system is a 486 EISA 
with two bus masters,  A Lance NE2100, and an Ultrastor 24F Scsi 
Controller.  The Panic seems to occur during heavy network and heavy SCSI 
activity.  Also the kernel prints "is0: MERR" a lot during heavy network 
load (This is equivalent to Linux's "Bus Master Arbitration Failure" 
Message).  Also, after this panic the SCSI bus appears to be hung.

Any ideas on how I could fix this?  Thanks.
