Hello Dave, Jeff, all
I just started experiments with a new setup consisting of:
00:00.0 Host bridge: ServerWorks CNB20HE Host Bridge (rev 23) 00:00.1 Host bridge: ServerWorks CNB20HE Host Bridge (rev 01) 00:00.2 Host bridge: ServerWorks: Unknown device 0006 (rev 01) 00:00.3 Host bridge: ServerWorks: Unknown device 0006 (rev 01) 00:02.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 0d) 00:03.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 0d) 00:04.0 Network controller: Elsa AG QuickStep 1000 (rev 01) 00:05.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07) 00:05.1 Input device controller: Creative Labs SB Live! MIDI/Game Port (rev 07) 00:07.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 00:0f.0 ISA bridge: ServerWorks CSB5 South Bridge (rev 93) 00:0f.1 IDE interface: ServerWorks CSB5 IDE Controller (rev 93) 00:0f.2 USB Controller: ServerWorks OSB4/CSB5 USB Controller (rev 05) 00:0f.3 Host bridge: ServerWorks: Unknown device 0225 01:02.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev 01) 01:04.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5701 Gigabit Ethernet (rev 15) 02:02.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5701 Gigabit Ethernet (rev 15) 02:03.0 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01) 02:03.1 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01)
I found out within minutes that this setup does not survive if you let the Broadcom cards share interrupts with anything else. It works ok now like this (eth2 is tg3):
CPU0 0: 343269 XT-PIC timer 1: 6804 XT-PIC keyboard 2: 0 XT-PIC cascade 5: 37952 XT-PIC EMU10K1 7: 515 XT-PIC HiSax 9: 711212 XT-PIC aic7xxx, aic7xxx, eth0, eth1 10: 4710570 XT-PIC eth2 11: 639316 XT-PIC ide2, ide3 12: 107821 XT-PIC PS/2 Mouse 15: 69222 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0
But horribly failed in such a setup:
0: XT-PIC timer 1: XT-PIC keyboard 2: XT-PIC cascade 5: XT-PIC EMU10K1 7: XT-PIC HiSax 9: XT-PIC eth2, aic7xxx, aic7xxx, eth0, eth1, ide2, ide3 12: XT-PIC PS/2 Mouse 15: XT-PIC ide1
I cannot even produce a "cat /proc/interrupts" for this because I am not fast enough at login (the network at eth2 is heavy loaded). I sometimes read about problems here with tg3-drivers, and I just wanted to point you to the shared case, maybe it has to do with this special case rather than with the drivers internals itself. (PS: its not the ide2-3, I checked that out)
