Hi, I have been struggling with a Dell Latitude C800 here. FreeBSD 4.1 and 4.3 was working with no problems, but when I tried to upgrade it to 4-stable, it did not see the disk anymore. It just gave this message: ######### atapci0: <Intel ICH2 ATA100 controller> port 0xbfa0-0xbfaf at device 31.1 on pci 0 ata0: at 0x1f0 irq 14 on atapci0 ... ata0-master: ata_command: timeout waiting for intr ata0-master: identify failed ######### At the end I tracked it down to these commits: src/sys/i386/i386/db_trace.c,v 1.35.2.1 2001/07/12 02:57:11 bsd src/sys/i386/i386/support.s,v 1.67.2.4 2001/07/12 02:57:11 bsd src/sys/i386/include/cpufunc.h,v 1.96.2.2 2001/07/12 02:57:11 bsd If I back those commits out, the machine boots and see the disk with no problems. Anybody have any ideas about it? John -- John Hay -- [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
