Description Wolfgang Hoffmann 2006-02-15 22:25:21 UTC

Most recent kernel where this bug did not occur: none yet  
Distribution: Ubuntu  
Hardware Environment: Marvel 88E8053 onboard NIC 
Software Environment:  
Problem Description: 
 
When transfering large amounts of data (e.g. rsyncing between two local 
machines), network hangs after some time (few minutes). dmesg doesn't give any 
messages. Removing the sky2 module and modprobing it back in cures the hang, 
i.e. transfer continues until the next hang. 
  
Steps to reproduce:  
 
As above

dmesg

The last messages in dmesg come from rmmod and modprobing the sky2 module.

Please tell me what more info I should provide.

2.6.16-rc5 still does hang OOTB, but reverting commit 
 
4d52b48b43d0d1d5959fa722ee0046e3542e5e1b is first bad commit 
    [PATCH] sky2: support msi interrupt (revised) 
 
_or_ turning off msi via module parameter (modprobe sky2.ko disable_msi=1) 
fixes the problem. 
 
Unless a fix for msi is at hand, may I suggest for 2.6.16 to revert this commit 
or switch the default to disable_msi=1?

MSI reverted in current drive 2.6.16.
