System: NetBSD Gstoder.nt.e-technik.tu-darmstadt.de 4.0_RC3 NetBSD 4.0_RC3 (SPG_PIII) #0: Thu Oct 25 18:49:17 CEST 2007 hf@Hochstuhl:/var/obj/netbsd-builds/4/i386/sys/arch/i386/compile/SPG_PIII i386
Architecture: i386
Machine: i386
>Description:

	After updating my i386 workstation from 4.0beta2 to 4.0rc3, I
	see frequent panics, especially during pkgsrc compiles or X11
	activity (like starting Acrobat Reader on a remote machine):

fatal double fault in supervisor mode
trap type 13 code 0 eip c037343c cs 8 eflags 10202 cr2 ccd6affc ilevel 0
panic: trap
Begin traceback...
uvm_fault(0xccd2feec, 0, 1) -> 0xe
fatal page fault in supervisor mode
trap type 6 code 0 eip c03a3c87 cs 8 eflags 14046 cr2 d ilevel 0
panic: trap
Faulted in mid-traceback; aborting...
dumping to dev 0,1 offset 1399
dump 1023 [...] 1 succeeded

rebooting...

	I can provide the core dump on request.

>How-To-Repeat:

	Upgrade to a NetBSD/i386 4.0rc3 installation (X11 server,
	icewm, bunch of pkgs), experience frequent failures.

	Used kernel configuration:

# IDE drives
# Flags are used only with controllers that support DMA operations
# and mode settings (e.g. some pciide controllers)
# The lowest order four bits (rightmost digit) of the flags define the PIO
# mode to use, the next set of four bits the DMA mode and the third set the
# UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
# to use, and the last bit must be 1 for this setting to be used.
# For DMA and UDMA, 0xf (1111) means 'disable'.
# 0x0fac means 'use PIO mode 4, DMA mode 2, disable UltraDMA'.
# (0xc=1100, 0xa=1010, 0xf=1111)
# 0x0000 means "use whatever the drive claims to support".
