Bug 13612

Summary:	"Timedout SCB handled by another timeout" on dual processor
Product:	Base System	Reporter:	Dr A W G Duller <andy>
Component:	kern	Assignee:	Justin T. Gibbs <gibbs>
Status:	Closed FIXED
Severity:	Affects Only Me
Priority:	Normal
Version:	3.2-RELEASE
Hardware:	Any
OS:	Any

Description Dr A W G Duller 1999-09-07 10:10:01 UTC

Under heavily loaded conditions (copying a 180Mb file at the same time
as image grabbing and processing using the Matrox Meteor card the
error message: "Timedout SCB handled by another timeout" appears and
all operations are performed extremely slowly (several minutes to
perform an ls). The only cure seems to be a reboot.

Fix: 

None known.
How-To-Repeat: 
It appears hard to duplicate when required but has happened twice, 
both times the Matrox Meteor was in use and the "/kernel: meteor0:
ioctl: tsleep error -1" appeared a few minutes before.

These types of problems indicate that ineterrupt delivery is broken. 
My guess is that the SMP issue that caused this problem has been fixed 
in a later release.  If that is not the case, please reopen a PR.
