Description ketan kothari 2007-02-08 22:41:35 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1

Description of problem:
When booting with kernel 2.6.19 and higher kernels on a Vmware virtual machine, the following error appears in a dmesg output. 

ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata2.00: (BMDMA stat 0x26)
ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x4a data 8 in
         res 51/50:03:00:00:00/00:00:00:00:00/a0 Emask 0x20 (host bus error)
ata2.00: configured for UDMA/33
ata2: EH complete

This started happening after upgrading from 2.6.18 to 2.6.19 and continue to appear with each newer kernel version. This is a Fedora Rwhide fully patched version. IF i boot with 2.6.18 kernel this error message does not appear.

Version-Release number of selected component (if applicable):
kernel-2.6.20-1.2922.fc7

How reproducible:
Always


Steps to Reproduce:
1. Boot with kernel 2.6.19 or higher
2. Open the terminal
3. type dmesg

Actual Results:
following output appears
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata2.00: (BMDMA stat 0x26)
ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x4a data 8 in
         res 51/50:03:00:00:00/00:00:00:00:00/a0 Emask 0x20 (host bus error)
ata2.00: configured for UDMA/33
ata2: EH complete

Expected Results:

Comment 2 ketan kothari 2007-05-16 18:19:26 UTC
The issue got resolved after I upgraded the vmware player from 1.0.4 to Version 
2. version 2 (2.0.0build-45731). The latest kernel version is 2.6.21-1.3149.fc7 
with which it is working fine.

One issue I encountered after installation of vmware player 2.0, that it gives 
the following ,message. 
Error while opening the virtual machine. The virtual machine appears to be in 
use. 
Deleting the .lck file from the directory that contains the image resolved the 
issue.
