I've had this problem for the past couple of days (I went a while between updates of my kernel since I was busy installing a new disk and moving OSes around). Just after the "waiting for SCSI devices to settle" message, I'll get a number of SCB errors (which I don't have written down, unfortunately), and then eventually a panic. This is with ACPI enabled... if I don't enable ACPI, it will proceed immediately to the panic. The panic is a "Trap 12: page fault in kernel mode". with "interrupt mask: cam <- SMP: XXX", and "Stopped at ahc_match_scb + 0x9d movl 0x2c(%eax), %eax" I apologize for the exceedingly lameassed manner of this bug report, I don't have serial ports enabled on this machine and don't know of a more effective means to get the details. With the kernel debugger, I get a stack trace similar to the following: ahc_match_scb(c0e7e000, c0e8e230, 0, 41, 0, 9, 1) ahc_search_qinfifo(c0e7e000, 0, 41, 0, 9, 1, 0, 1) ahc_timeout(c0e8e168, 40000000, 0, 0, ffffffff) softclock(0, 18, c02b0010, 10, ffffffff) doreti_swi() I can dig up my kernel config and a "functional" dmesg as soon as I get back via the saved good kernel. For the record, this is via the onboard AIC-7890 on a Tyan Thunder/100 dual processor board running an SMP kernel. -- Brandon Hume - hume -> BOFH.Halifax.NS.Ca, http://WWW.BOFH.Halifax.NS.Ca/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
