I've seen this on another driver as well, and the cause has been found recently. The change to make scsi drivers (only the ones that have the ability and are tested) use "high memory" directly instead of needing bouncebuffers had a small (but of 3 drivers significant) sideeffect in how some normal requests were handled; this exposed bugs in codepaths that before never were executed. This change of behavior has been corrected in kernel 2.4.9-0.12 (and later), which hopefully will appear in rawhide soon. Thank you for the report; this means that I'll have to check this driver for the bug (eventhough that codepath isn't executed). Is this the "use sg only for >1 chunk" bug? This bug should be reopened. It is _NOT_ fixed in kernel 2.4.9-0.18. I am able to get further along in the boot process than before in that the partition table is now readable but shortly thereafter I get the same message as before: AAC: NMI ISR: NMI_DMA_0_ERROR followed by a pause of 20-30 seconds, then endless SCSI errors. The three fingered salute brings the machine down cleanly. |
