Could this be the reason for the reported slowdown in the last six months? Can you elaborate? There's an unexplained slowdown of kernel 2.6 detailed in this thread: http://kerneltrap.org/node/4940 I don't want at all to justify it with the change you talk about in gas, but maybe it is worth to check if it has anything to do with it. The slowdown happened in this last six months. -- Pau - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

The old assembler accepts it and turns it into "movw %ds,(%eax)". I disagree. Violently. As does the old assembler, which does not turn "mov" into "movw" as you say. AT ALL. I should have made myself clear. By "movw %ds,(%eax)", I meant: 8c 18 movw %ds,(%eax) That is what the assembler generates, and should have generated, for "movw %ds,(%eax)" since Nov. 4, 2004.

processes stuck in D state
Since 2.2.4-ac28 and 2.4.3 I keep on getting processes in D state that I cannot kill, usually mozilla or nautilus which use a large amount of RAM. Today is galeon: A ps -eo pid,stat,pcpu,nwchan,wchan=WIDE-WCHAN-COLUMN -o args shows the following: 11520 D 0.0 105db1 down_write_failed /usr/bin/galeon-bin This didn't happen neither with 2.4.2 nor with 2.4.3-pre7; I'm not sure about pre8.

2.4.2-ac26 -> processes in D state
I've tried 2.4.2-ac26 to test the new xircom_cb driver but I have had to reboot on 2.4.3-pre7 as some processes got stuck on D state. The processes were large apps: once nautilus and once mozilla. I couldn't get any other information.

I use: alias eth0 xircom_tulip_cb and when this happens -90% if times when I boot and 100% of time when I awake after a sleep- I just do the following: ifconfig eth0 -promisc and it works again.
