I'm running on a Gateway PIII/600, 256M ECC SDRAM. I get a similar kernel panic (trap 19 with interrupts disabled, and an ECC error) when I attempt to use the soundcard. It's detected completely normally. Is this still a well-known and being-worked-on thing, or should I send verbose dmesg output and kernel config? apm0 enabled, per GENERIC. Major differences from generic: IPFIREWALL (+VERBOSE, +DEFAULT_TO_ACCEPT, +DIVERT, +DUMMYNET) HZ=10000 NMBCLUSTERS=8192 no scsi, pared down ethernet interfaces, added 4 bpf devices. -Dave -- work: dga@lcs.mit.edu me: dga@pobox.com MIT Laboratory for Computer Science http://www.angio.net/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
