After updating to yesterday's -CURRENT, my IBM Thinkpad A22m stoped booting. It hangs at: GEOM: create disk ad0 dp=0xc3ded670 ad0: 38154MB <IC25N040ATCS04-0> [77520/16/63] at ata0-master UDMA33 ata1: resetting devices .. done The console is still alive, but the kernel appears to be waiting for an interrupt that will never come. My Thinkpad is known to have a buggy ata controller which (sometimes? all the time?) fails to send interrupts for ata1-slave, and causes various revisions of the kernel to complain in various places. -CURRENT used to complain at boot, and the most recent working kernel I have complains at shutdown. The most recent working kernel, from earlier this week: GEOM: create disk ad0 dp=0xc3ded670 ad0: 38154MB <IC25N040ATCS04-0> [77520/16/63] at ata0-master UDMA33 acd0: DVDROM <HITACHI DVD-ROM GD-S200> at ata1-master PIO4 Mounting root from ufs:/dev/ad0s3a at shutdown: syncing disks, buffers remaining... 3 3 1 1 done Uptime: 2m21s ata1-slave: WARNING - FLUSHCACHE recovered from missing interrupt -- Brian Buchanan, CISSP bwb@holo.org -------------------------------------------------------------------------- FreeBSD - The Power to Serve http://www.freebsd.org
