[Bug 438263] New: b44: constantly "powering down PHY" during high network load after resume
https://bugzilla.novell.com/show_bug.cgi?id=438263 Summary: b44: constantly "powering down PHY" during high network load after resume Product: openSUSE 11.0 Version: Final Platform: 64bit OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: andreas.pfaller@gmail.com QAContact: qa@suse.de Found By: Community User On my Dell Inspiron 1720 Laptop the b44 network driver constantly reports "powering down PHY" during some high network load after a resume from "Suspend to RAM", e.g. ..

Light network usage after "Suspend to RAM" also does not trigger the problem. This problem is 100% reproducable e.g. with "bonnie -s 2048" on an mounted nfs share (the problem only starts at the start of bonnies "rewriting" test) or when the laptop takes part on a bigger "icecream" compile. If the load decreases (e.g. ^C of bonnie) the interface recovers after some time and is usable with light network load (e.g. ssh). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

No change regarding the problem while using the provided 2.6.25.19-0.2-default kernel from comment #2. Since I had no source for the provided kernel I had to do my bonnie test from runlevel 3 after "s2ram" (I normally use a self compiled nvidia driver and use the kde applet for suspend). The provided kernel also failed to enable the display after resume so bonnie was started from an ssh session. (I never tried a suspend from runlevel 3 before so I don't know if this problem exists with 2.6.25.18-0.2). Some other observations: bonnie throughput after fresh reboot (nearly identical with 2.6.25.18-0.2 and your 2.6.25.19-0.2): Bonnie 1.4: File './Bonnie.4545', size: 2147483648, volumes: 1 Writing with putc()... done: 11379 kB/s 25.4 %CPU Rewriting... done: 5715 kB/s 2.0 %CPU Writing intelligently... done: 11439 kB/s 2.4 %CPU Reading with getc()... done: 11114 kB/s 33.2 %CPU Reading intelligently... done: 11319 kB/s 1.8 %CPU Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done... ---Sequential Output (nosync)--- ---Sequential Input-- --Rnd Seek- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --04k (03)- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU i1720 1*2048 11379 25.4 11439 2.4 5715 2.0 11114 33.2 11319 1.8 1430.1 5.0 bonnie throughput after resume (also nearly identical with both kernel versions). Note the greatly reduced throughput (there are no "powering down" messages during this part of the test): Writing with putc()... done: 7874 kB/s 15.2 %CPU As I said in my original comment the "powering down" problems start during the rewrite phase of bonnie so I can't provide throughput numbers for the later bonnie stages. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As a workaround for openSUSE 11.0, you can use the mentioned kernel from SLES11/openSUSE 11.1 (please note that you won't get automatic kernel security updates this way). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
