ad4: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - on FreeBSD 6-STABLE

[Peter van Heusden]

Hi

After my previous email about the SETFEATURES SET TRANSFER MODE timeout 
on (msgid 441AA807.5090100 at wfeet.za.net , 17 March 14:18 GMT + 2 on 
freebsd-stable), I installed FreeBSD 6.1 BETA 4 and upgraded to a 
6-STABLE kernel, running the box in 'safe' mode to do so. I now, 
however, get a slightly different error message:

ad4: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing

ad4: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing

ad4: WARNING - SETFEATURES ENABLE WCACHE taskqueue timeout - completing 
request directly
ad4: WARNING - SET_MULTI taskqueue timeout - completing request directly
ad4: FAILURE - WRITE_DMA timed out LBA=32804495

(The address after LBA is not always the same)

This is with ad4 as a Seagate ST320423A on a Promise PDC20262 UDMA66 
controller.

Any suggestions?

Thanks,
Peter
