After compiling v2.6.24-rc7-163-g1a1b285 (x86_64) yesterday I suddenly see this error repeatedly: kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang kernel: Tx Queue <0> kernel: TDH <a> kernel: TDT <a> kernel: next_to_use <a> kernel: next_to_clean <ff> kernel: buffer_info[next_to_clean] kernel: time_stamp <10002738a> kernel: next_to_watch <ff> kernel: jiffies <1000275b4> kernel: next_to_watch.status <1>
My previous kernel was v2.6.24-rc7 and with that this error did not occur. I have also never seen it with earlier kernels. The values for "TX Queue" and "next_to_watch.status" are constant, the others vary.
