[lc-devel] [BUG] 2.4.19-0.24pre5 pached against 2.4.20 with O(1)

[Andre M. <an...@co...>]

Hello All,

I've run into a problem with patch 2.4.19-0.24pre5 against my 2.4.20
(Including O(1) scheduler, and Neil Schemenauer's IO elevator patch).

This run's on a PentiumIII 700Mhz UP, on a 440BX main-board.

Funny enough. This occurred when starting java 1.4.1_02-b06 in galeon
running an applet.

Any help would be appreciated, and please CC me since I'm not on the
list.

Re: [lc-devel] [BUG] 2.4.19-0.24pre5 pached against 2.4.20 with O(1)

[Rodrigo S. de C. <rc...@im...>]

Hi Andre.

I have already got a bug report exactly like yours (from
Marc-Christian Petersen) in December (yes, the project was sort of
hibernation process). This bug seems to be fixed in the CVS version,
which will be sometime released as 0.24pre6. The CVS version is for
2.4.20, but it is currently unstable.

Thanks for the report, anyway. As soon as 0.24pre6 is released, I
would like you to give it a try to check if the bug is gone.

Best regards.
