Hi all, I hope this is the right place to ask; I've searched the mailing lists and can't find any comments, so I hope it's not just me! 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
