Today, I came across a problem; sorry, I have failed in trying to spot the cause... [1.] Linux V. 2.6.3 panics with "Buffers at physical address >16Mb used for aha1542" at boot time on my box. [2.] Up to Linux-2.6.1-rc2, everything went fine on my somewhat aged box with both AHA1542 and AIC7xxx-based SCSI controllers. After upgrading to Linux-2.6.3 (essentially with the same .config file, using make oldconfig), my box failed to boot with this message: buf vaddress e7f8be5c paddress 0x27f8be5c length 16 Kernel panic: Buffers at physical address >16Mb used for aha1542 Nothing short of a hard reset let out of this... [3.] AHA1542, DMA (?)
