NetBSD hostname 2.0 NetBSD 2.0 (GENERIC) #0: Tue Nov 30 21:04:03 UTC 2004  builds@build:/big/builds/ab/netbsd-2-0-RELEASE/alpha/200411300000Z-obj/big/builds/ab/netbsd-2-0-RELEASE/src/sys/arch/alpha/compile/GENERIC alpha
>Description:
When using the generic kernel, my lsi 53c896 based scsi adapter is recognised by the esiop driver. This driver quite regularly panics my system: sometimes it will panic during shutdown, preventing the kernel from syncing discs, sometimes it will panic during CVS checkouts, etc. Generally at inconvenient moments while there is (heavy) filesystem activity. I haven't experienced this with the siop driver. 
>How-To-Repeat:
Get a system with an LSI 53c896 card, and generate some heavy filesystem activity. With some "luck" it will panic.

 Can you give more details about the panic ? Especially, a stack trace from ddb
 would be nice (type 'tr' at the db> prompt).
