Can you post the output of 'lspci -n' please? Created attachment 342282 [details]
lspci -n output
Attached is the lspci -n command output.
Actually I haven't seen this anymore since I upgraded to kernel-2.6.18-140.el5.x86_64
It was not happening all the time before the upgrade. I'll keep an eye for it for a while.
I'm going to close this based on comment 2. Please reopen if the problem persists with current kernels from here (or the actual RHEL 5.4 release kernel): http://people.redhat.com/dzickus/el5/ Suspending was working somehow till 2.6.18-164 Now with 2.6.18-164.2.1 first or second or third suspend crashes. If I disable wlan from the switch I can suspend as many times I want. So the wlan and suspend problems are definitely related. The only clue is still this message which appears after a while: iwlagn: No space for Tx iwlagn: Error sending REPLY_STATISTICS_CMD: enqueue_hcmd failed: -28 Also, without the wlan on suspending is faster. When wlan is on it takes more time to suspend, looks like it is moving in slow motion. I noticed that I get these in the syslog when computer is connected to wlan (wlan disconnects by itself sometimes): BUG: warning at include/../net/mac80211/rate.h:153/rate_lowest_index() (Not tainted) Call Trace: [<ffffffff882f7784>] :iwlagn:rs_get_rate+0x176/0x1b2 [<ffffffff882263a2>] :mac80211:rate_control_get_rate+0x85/0xe5 [<ffffffff8822b360>] :mac80211:ieee80211_tx_h_rate_ctrl+0x31/0xfa [<ffffffff8822bf5e>] :mac80211:ieee80211_master_start_xmit+0x226/0x3fc [<ffffffff80239147>] __qdisc_run+0x136/0x1f9 [<ffffffff8002f9cb>] dev_queue_xmit+0x150/0x271 [<ffffffff882256f1>] :mac80211:ieee80211_sta_work+0x50f/0x720 [<ffffffff882251e2>] :mac80211:ieee80211_sta_work+0x0/0x720 [<ffffffff8004d80f>] run_workqueue+0x94/0xe4 [<ffffffff8004a057>] worker_thread+0x0/0x122 [<ffffffff8009f9f5>] keventd_create_kthread+0x0/0xc4 [<ffffffff8004a147>] worker_thread+0xf0/0x122 [<ffffffff8008c3c2>] default_wake_function+0x0/0xe [<ffffffff8009f9f5>] keventd_create_kthread+0x0/0xc4 [<ffffffff8009f9f5>] keventd_create_kthread+0x0/0xc4 [<ffffffff8003298b>] kthread+0xfe/0x132 [<ffffffff8005dfb1>] child_rip+0xa/0x11 [<ffffffff8009f9f5>] keventd_create_kthread+0x0/0xc4 [<ffffffff8003288d>] kthread+0x0/0x132 [<ffffffff8005dfa7>] child_rip+0x0/0x11 Please also make sure you have the lastest available firmware package for your wireless device. Also, please try the test kernels here: http://people.redhat.com/linville/kernels/rhel5/ Do these kernels work better for you? Ok, The wlan part seems to work faster and better. Waking up from suspend sometimes freezes with kernel-2.6.18-175.el5.jwltest.96.3.x86_64 and latest v2 firmware. The trouble of going in to suspend seems to have gone away. I have got also couple of kernel panics when waking up from suspend. Any chance to get a logs (serial console, netconsole, kdump) when kernel do resume and crash ? Maybe if you send a link to instructions howto use netconsole or kdump Sure Kdump: http://kbase.redhat.com/faq/docs/DOC-6039 Don't know about RHEL netconsole howto, here is fedora doc: https://fedoraproject.org/wiki/Netconsole Easiest way to setup netconsole on RHEL is edit /etc/sysconfig/netconsole file and run "/etc/init.d/netconsole start". I'm not sure if such debugging options will be useful, it depends if proper subsystems initialize before kernel resume crash. Please let as know. I'm sorry, I can't find time to debug this... As of kernel-2.6.18-194 the suspend bug when wireless network is on seems to have been fixed. I glad this is fixed (please reopen if not). Thanks. |
