I'm following the current development branch and all has been (generally) okay until the 29th of aug, since when I've been unable to get the kernel to boot successfully; initially the messages are strewn with "can't allocate register resources" (sorry, I don't have the exact details as they scroll off the screen before I have a chance to grab them and I can't capture dmesg since it's not booting successfully) After it starts the 2nd CPU and tries to access the Adaptec 7895 I get the following messages over and over: ahc0: ahc_intr - referenced scb not valid during SELTO (31, 255) ahc1: ahc_intr - referenced scb not valid during SELTO (31, 139) After a while the system may panic with the message: (probe0:ahc0:0:0:0): SCB 0x9 - timed out while idle, SEQADDR == 0xb panic: Waiting List inconsistency. SCB index == 255, yet numscbs == 20 The system I'm using is a dual Pentium III, Tyan Thunder DLUAN1658 BX motherboard, onboard Adaptec 7895 dual-channel UW scsi. Fairly unexciting setup overall. Anybody got any ideas? Cheers, Chris. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
