RELENG_5: ata interrupt problems

[Kent Hauser]

Hi,

I updated my IBM T41 from a May -CURRENT to -RELENG_5 & am now getting 
"READ_DMA interrupt but timeout fired" (also WRITE_DMA). After a minute or so 
it drops into the debugger. Kernel is unmodified GENERIC.

From the archives, I've seen some chatter about this for the last month, but I 
can't find the solution posted.

Any thoughts? (Or research I need to do?).

Thanks, Kent
