(and they are being rejected) I can't think of the likely reason, but note that the limit of 17 DMA segs was actually 16 on some early 1542 cards. (this is a limit in the driver.. you may want to try recompile aha1542.c with this limit lowered.. but that won't help THIS problem.. for This problem, the request never even gets to the card. The driver is rejecting it as bad (The region to be written extends over > 17 pages). though, it sounds as thought the entire transfer is strange.. (block -1?) looks as if the inode writing code has for some reason decided to write strange objects. the error mesages should be: >aha0: aha_scsi_cmd, more than 17 DMA segs <---from aha driver >sd2: oops not queued <------from disk driver >bad block -1, ino 3456 <------ who writes THIS message? julian
