 |
|
There are a couple of messages in the system log from the kernel that I don't understand and would appreciate help decoding.
The most obvious is messages like
| Code: | ata1.00: configured for UDMA/133
ata1: EH complete |
for ata1-4 (I have 4 SATA disks). This appears well after the kernel has finished booting (after I've logged in). Googling, EH seems to stand for error handling. There are only SATA disks in the system so, is UDMA/133 the correct speed? I thought that was the max speed for PATA disks and that SATA disks should be faster. Anyone have any idea what this means?
The next is
| Code: | | hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj |
I have no idea what this means and if I should do anything to fix it. Anyone know?
I get messages like this during boot up
| Code: | | calibrate_delay_direct() dropping max bogoMips estimate 3 = 3367146 |
Is that part of the normal process of estimating bogoMIPS or, is it indicating a problem?
Finally, I get
| Code: | | Disabling lock debugging due to kernel taint |
after the Ati proprietary drivers (fglrx) are loaded (which is the reason for the kernel taint). Can I disable lock debugging or, is it always enabled?
Any information would be much appreciated. |
