Sure: http://lkml.org/lkml/2010/1/13/342 http://lkml.org/lkml/2010/1/15/245 BTW setting the JMB363 mode in BIOS setup from IDE to AHCI or RAID (thus enabling JMB363 BIOS) changes nothing. The only weird thing is that some time ago the problems weren't there. It could be genuine hardware problem. I have full kernel logs. Sometimes the same kernel (build) is "good" at one time and "bad" at another. I had booted the board (with JMB363 and the driver enabled) 57 times. Out of these, there was no problems 16 times (date-hrs-result): 08-18-start-good 08-18-23:21-good 08-20-12:21-good 08-20-12:41-good 08-20-13:40-good 08-20-13:52-good 08-20-13:54-good 08-20-14:06-good 08-20-16:16-good 08-20-20:53-good 08-21-11:15-bad 08-22-12:10-good (uncertain, the kernel had other problems) 08-22-12:12-bad 08-22-22:36-bad 08-22-22:39-bad 08-22-22:40-bad 08-23-12:53-good 08-23-13:31-good 08-23-19:22-good 08-24-14:44-bad 08-25-12:29-bad 08-26-12:34-bad 08-27-12:43-bad 08-27-12:51-bad 08-27-18:26-bad 08-28-12:10-bad 08-29-11:38-bad 08-30-22:13-bad 08-31-12:50-bad 09-01-12:53-bad 09-01-17:47-good 09-02-12:42-bad 09-02-18:27-bad 09-03-11:56-bad 09-04-13:40-bad 09-04-22:23-bad 09-05-21:42-good 09-06-16:42-bad 09-07-14:13-bad 09-08-14:21-bad 09-09-13:47-bad 09-10-12:24-bad 09-10-23:33-bad 09-11-14:07-bad 09-12-01:43-bad 09-12-12:29-bad 09-12-23:11-bad 09-12-23:42-bad 09-13-01:11-bad 09-13-13:45-bad 09-13-17:53-bad 09-13-18:01-bad 09-13-19:13-bad 10-18-00:59-bad 10-18-17:07-bad 10-18-17:14-bad 10-18-17:19-bad There are no significant kernel log differences between *good and *bad (excluding the AHCI messages). Sometimes the exceptions were sporadic, like in 09-01-12:53-bad case: Sep 1 12:53:38 Machine booted Sep 1 13:02:33 ata8: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen Sep 1 13:02:33 ata8: irq_stat 0x00000040, connection status changed Sep 1 13:02:33 ata8: SError: { CommWake DevExch } Sep 1 13:02:33 ata8: hard resetting link Sep 1 13:02:34 ata8: SATA link down (SStatus 0 SControl 300) Sep 1 13:02:34 ata8: EH complete Sep 1 15:47:12 Machine rebooted Perhaps I should really check these resistors around the JMB363 chip, and maybe using a vacuum cleaner is a good idea? I think I will do. It's certaing there was nothing connected do JMB363 SATA. I don't know BIOS versions and CMOS (BIOS) configs. -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
