>Organization:
Fachhochschule Lippe, Lemgo, Germany
>Environment:
i386 4.2-RELEASE kernel
SMP (2xPPro)
>Description:
when enableing dma lpt support via
lptcontrol -e /dev/lpctl0
on an ECC capable parallel port, the kernel panics
panic: isa_dmastart: bad bounce buffer
mp_lock = 00000001; cpuid = 0; lapic.id = 00000000
Debugger("panic")
Stopped at Debugger + 0x34: movb $0, in_Debugger.579
Exactley the same configuration had worked on a 3.X System for
several month on the same hardware.
A core dump is available.

# The flags takes the following meaning for apm0:
# 0x0040 Use the segment limits that the BIOS reports.
# 0x0020 Statclock is broken.
# 0x0011 Limit APM protocol to 1.1 or 1.0
# 0x0010 Limit APM protocol to 1.0
# If `options VM86' is set, V86 mode is used in APM initialization
# instead of real mode. VM86 is recommended if you want to use APM.
