Comment 1 Peter Robinson 2003-03-05 15:35:39 UTC
It looks like this bug has been fixed in the driver update as per kernel 2.5.64

Quoted from the kernel changelog. Which appears to be the problem I have been

I think this is happening in earlier versions of Redhat as well (specifically
8.0 and possibly 7.3)

[PATCH] trident 1/3 fix "did not come out of reset"
The M5451 can sometimes not come out of reset. This is non fatal and it
continues to work fine, so print a nasty message but don't fail the driver

[PATCH] trident 2/3 make me the maintainer
Make Muli Ben-Yehuda the maintainer for trident as per Alan's suggestion

[PATCH] trident 3/3 use pr_debug instead of TRDBG
use the standard pr_debug macro instead of TRDBG

I have the same problem on Acer Travelmate 525txv, but did not have it in RH8.0.
The computer totally freezes during modprobe.
