Subject: pcnet32 79C972 doesn't survive suspend to RAM
Date: Sat, 28 Jul 2007 18:56:51 +0200 [thread overview]
Message-ID: <200707281856.51591.ak@suse.de> (raw)
Hallo,
I tried suspend to RAM on my desktop. Surprisingly near everything worked
after the wakeup, except for the pcnet32 PCI card. Kernel is 2.6.23-rc1-git4
on x86_64.
Bootup:
pcnet32.c:v1.33-NAPI 27.Jun.2006 tsbogend@alpha•franken.de
IOAPIC[0]: Set routing entry (2-21 -> 0x81 -> IRQ 21 Mode:1 Active:1)
ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 21 (level, low) -> IRQ 21
pcnet32: PCnet/FAST+ 79C972 at 0x1100, 00 a0 d2 18 9d 21
tx_start_pt(0x0c00):~220 bytes, BCR18(9861):BurstWrEn BurstRdEn NoUFlow
SRAMSIZE=0x1700, SRAM_BND=0x0800, assigned IRQ 21.
pcnet32: Found PHY 7810:0003 at address 1.
eth1: registered as PCnet/FAST+ 79C972
pcnet32: 1 cards_found.
After the S3 wakeup I get:
NETDEV WATCHDOG: eth4: transmit timed out
eth4: transmit timed out, status 0053, resetting.
NETDEV WATCHDOG: eth4: transmit timed out
eth4: transmit timed out, status 0053, resetting.

... going on ...
And no packets are getting received either.
