Description Felix Seeger 2005-12-12 11:06:18 UTC
During boot with an Adaptec 2100S card, 4 drives attached (1 single, 3 as 
raid5 array) the system hangs on Debian stable. 
 
 
Here is a part from the console I've written down: 
 
iop0: controller found   
PCI: Unable to reserv mem region ... for device ...(iop0)   
iop0: device already claimed   
iop0: DMA/IO allocation fopr I2O controller failed   
...   
...   
dpti0: Trying to abort cmd=56   
  
The system hangs here, bootup with 2.6.8 from Debian works fine, I am 
compiling older kernel versions atm. The raid array and disks where detected 
correctly prior to the messages above.

User loaded both dpt and i2o drivers for the same card. 

By 2.6.16rc1 the i2o code for this appears correct and it skips the device at
this point.

Please test a current kernel.

OK. thanks.  Felix, can you please test 2.6.16-rc1 and update bugzilla
appropriately?

Mark, you chopped bugme-daemon off the Cc: list.  Please retain it, so this
stuff gets filed into bugzilla, thanks.

Please reopen this bug if it's still present in kerenl 2.6.16.
