It does indeed have a Qlogic SCSI chip. I've been talking with the maintainer of the isp driver, and he doesn't know about anything like this. The most recent driver continues to result in a kernel that tries to deliver these bogus SIGPROFs. The machine is now at 4.1.1-RELEASE (it's not actually there quite yet -- since I can't remotely reboot the damn thing, but the latest isp driver plus the ispfw driver didn't help). > > Regards, > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-stable" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
