Sorry, I hosed my canonical mapping in Postfix. Use <matthias.andree@web.de> to reply. One more way to reproduce this: "atacontrol reinit 1" will also reset the primary master to UDMA33 (when it was UDMA66 previously) If there is anything I should look at with a serial gdb attached, let me know. Of course, that's "secondary master" Responsible Changed From-To: freebsd-bugs->sos Over to ATA maintainer. State Changed From-To: open->closed This is belived fixed. |
After waking up from APM standby mode, the IDE interfaces are reset, and my Secondary Master (ad2), which was in UDMA 66 before, is in UDMA 33 mode henceforth. dmesg: resumed from suspended mode (slept 00:00:01) ata0: resetting devices .. done ata1: resetting devices .. ad2: DMA limited to UDMA33, non-ATA66 cable or device done ad2: DMA limited to UDMA33, non-ATA66 cable or device I know for sure I have short 80-ribbon connectors for all drives, and on initial boot-up everything is fine, dmesg again: ad0: 58610MB <Maxtor 4W060H4> [119081/16/63] at ata0-master UDMA66 ad2: 43979MB <IBM-DTLA-307045> [89355/16/63] at ata1-master UDMA66 ad3: 19470MB <WDC AC420400D> [39560/16/63] at ata1-slave UDMA66 This cannot be cured with atacontrol: # atacontrol mode 1 UDMA66 UDMA66 Master = UDMA33 Slave = UDMA66 options ATA_STATIC_ID is enabled. Here's the list: ATA channel 0: Master: ad0 <Maxtor 4W060H4/AAH41310> ATA/ATAPI rev 6 Slave: no device present ATA channel 1: Master: ad2 <IBM-DTLA-307045/TX6OA6AA> ATA/ATAPI rev 5 Slave: ad3 <WDC AC420400D/J58OA30K> ATA/ATAPI rev 4 Fix: unknown. No workaround known other than reboot. How-To-Repeat: apm -Z dmesg
